So a little backstory of myself, I'm in my mid 30s AFAB. I have been secretly struggling with gender issues since my mid-teens. When growing up I never felt comfortable in female clothing even though I was made to wear them, because that's what "girls" were supposed to do. I grew up not wanting to play with dolls but help my dad fix the car or do other boy things. Anyways, into my teens I started to feel like I didn't fit in, mostly in myself, like I wasn't who I really was on the inside. I didn't feel like I could talk to anyone about this because I felt like I would get made fun of and people would think I was absolutely crazy. I started to develope really bad depression and had thoughts of suicide because I felt like I couldn't talk to anyone about it. I struggled through my depression and feelings throughout my teenage years, I never told anyone because of fear. In my late teens I met my current partner, who happens to be trans, I felt with them I could let myself go a bit but I never said anything about my feelings, I cut my hair extremely short and it was liberating even if it wasn't changing myself a ton, it was a small step and it felt good. We have been together for over ten years now and throughout that time I have still had the same thoughts I have had since I was a teenager, that i externally do not match what I feel I am internally. I stare at myself sometimes and wonder what I'd look like if I could actually look like how I feel, hell my dreams I'm not female I'm male. I don't know why it is so hard for me to talk to my partner about this, I know it shouldn't be. I have so many fears about opening up about this, about telling my family, about actually starting because of my job. My partner now knows though and it feels good to have let one person know but it's still very very scary at the same time. Within the past 3-4 my depression has reached an all time low, I'm on and take meds everyday but they aren't working I have bad thoughts pretty often but I'd never do anything because I couldn't leave my partner and I enjoy my career even though I'm scared ->-bleeped-<-less that if I do this I may not have a career afterwards, my family will disown me I'm pretty sure of it, and I I only have two really good friends that I feel like I could talk to that I know are open minded but I'm still afraid to lose them.
I guess what I'm looking for is advice, kind words, maybe some support. Anything would be greatly appreciated.
