Well this is just from my experience and everyone's is different but...
I started HRT at around 22/23 and was very excited and happy to be on that path. At the time I was very androgynous had very long hair down to my waist (thanks to extensions

) never wore dresses or anything unless going out to the clubs, but did dress very girly. Crop tops and capris etc etc.. I never left the house without makeup and was gendered female a lot, and by those who knew me thought of me as trans before I started to transition.
I was living in Los Angeles at the time, so I never stuck out too much. I got stares from curious people etc, but I was never harassed and was actually hit on even by straight guys occasionally. I always got a lot of complements about how pretty I was, being compared to Jennifer Garner in her "Alias" days as that was a new show at the time lol. At any rate I was doing quite well and comfortable being very girly. I even came out to my mom, I went to visit her at her house a few hours away. I brought my regular clothes not to wear but to show her how I normally present myself. She actually took it well, but from what I remember she was nervous how my 2 sisters and 2 brothers would take it.
I'm the youngest out of 5 which I think had a lot to do with my de-transitioning. As soon as my nipples changed and my chest felt a little heavier I got very nervous. I just thought how am I ever going to pull this off. My brothers will kill me, and my sisters what would they think?? And my niece's and nephews whom I was very close to would think I was a freak and would come to be embarrassed by me. All of these fears just screamed out to me to stop what I was doing! I'm almost 6'2" have a size 12 foot and a cleft chin. I just thought of all the money it might cost me with electrolysis possible FFS and never did I actually want SRS so maybe I was just confused, or so I convinced myself. I was struggling at school at the time and was out of a job living off of student loans. I kind of freaked out, dropped out of school got a full time job at a print shop. The dress code was very strict unlike where I used to work which was a beauty supply with little to no dress code. Instead of wearing tight shirts and hip huggers and long extensions makeup and nail polish. I was now wearing a blue dress shirt khaki's and loafers. Nail polish and makeup and jewelry was not allowed unless very minimal even for the woman employees. So it was pretty much "boy" time and it translated into my personal life. I just kind of dropped out, and started to go through my guy phase. Ironically I grew my own hair out at the time, maybe a subconscious way of having something girly about me...idk. I started to sport a short goatee from time to time for the first time in my life (this was around 25/26). I didn't go out I stopped talking to friends and I lived at work, moving my way up is all I cared about.
Luckily around that same time I met my now husband of 9 years. From time to time I would wear makeup when going out but it was guyliner and such nothing actually femme. Being that I just turned 35 recently I kind of had a light bulb go off a few months ago. I just thought about my life and the last 10 plus years, how I kind of dropped out and haven't really truly been myself for a decade!! So much time lost

I had this realization OMG I Do NOT want to be a man, and I DEFINITELY do NOT want to be an OLD man! I mean aging is aging, but I thought I have to start HRT NOW the sooner the better. I realized that I was ALWAYS a girl and that it's easy to get the lines blurred between femme, gay boy, drag, androgyny and trans etc. When I really break it down and think what I really identify with it would be trans/genderqueer. I thought back to my childhood and yes I wanted to be a girl as early as 4 years old. All the signs were there, it was just easier to be a "gay boy".
I know I may not have the luck of ever looking like a real woman, but I would like to get as close as I can. I feel a very strong connection to the queer community, as I always have. So I have no problem with this, I'm actually happy with being queer. I still haven't come out to anyone as trans yet but my therapist and husband who has accepted me 100% (thank God, don't know what I'd do without him!) I'm just taking it one day at a time. Yesterday at work a customer who is in several times a week greeted me with female pronouns before she caught herself and apologized. That hasn't happened in years and if felt AMAZING!!
I guess to sum it all up I detransitioned because I thought I'd never be 100% female. I was right, I wasn't born female, but I feel the way I do and that won't go away. Some transition easier than others, I think right now I stand somewhere in the middle and before that made me nervous now I'm totally okay with it. So now that I started HRT barely a month ago I'm very happy and excited. There was a short time after I detransitioned where I too was feeling pretty awesome about being a guy experimenting with facial hair etc. I think though in reality that was only for a few short months, and looking back it was more like being in drag. I think for the most part I repressed my feelings and became someone who didn't care about much anymore besides my career and my man and my dog, I stopped caring about me!
I'm struggling with 10 years lost, 10 years I could have been transitioning all the changes that I would have gone through. How I could have lived my life how I wanted to live it, how I could have just toned it down in front of family if it was that big of a deal. I know for a fact my family would never disown me, they are conservative (not in a religious way though) so it could have been done then just as I am doing it now. I think about how much happier I probably would have been and adjusted myself into being comfortable with my body and my presence and my identity. All those things that take so much time to work on, could have been done.
I have to stop myself though and think about how lucky I am to have such a brilliant caring loving husband and the life we have built together with our 2 dogs and how much I love our little family. How he has accepted who I am and what changes are about to happen. I'm so blessed to have him as my partner in life and that I've come full circle and am now ready to accept myself. I believe everything happens for a purpose, I believe I wasn't ready then but I'm ready now. We all wish a lot of things, and we all regret a lot of things. I can only be happy that I'm still young, even if not in my 20's and that I now am excited about life again!!
I'm only telling my story for not only you but to share with others. I'm not saying you're making a mistake and that you'll be back at it in a few years. I think we all need to be happy with ourselves and be okay with that. I just think I thought I was okay, but deep down inside I knew I was not okay. It wasn't till very recently I knew that this was serious and that I needed to do what I needed to do to make me happy for the remainder of my life
