Your journey sounds like one of both wonderfulness and setbacks, some combination of those is necessary for every life, but I think in trans people the setbacks often seem harder because so few people can relate to exactly what we face.
At 3+ yrs on hormones, much of physical change is complete. Like you, I changed rapidly and early. I have 38D breasts (DD when my weight goes up, my body looks incredibly feminine. I still have privilege and I "should" feel blessed
The price has been huge losses, in family and friends (including my initially accepting marriage). Depression returned after initially losing the GD, have left me at times, with a feeling of loss of momentum and yeah that makes me question why on earth, I ever did this.
In the three years, my presentation has gone from tomgirl/androgynous to quite girlie, now back to more tomgirl. I sometimes believe we gravitate back to what we know in times of stress, even if what we know is not entirely perfect for us. I don't have any guy clothes anymore but I do find some solace in some level of masculinity at times and I won't be ashamed of that. I often remind myself that there is no right way to be a trans woman. I still get correctly gendered 90% of the time.
What I did gain though was a lot. New love, friends that truly understand me and the ability to be my authentic self without passing myself through the filter of other people. I think what you have faced is pretty common and only you can decide how to proceed, but there are many that face exactly what you have.
