To my big surprise my psychiatrist suggested to remove the BPD diagnosis from my mental health record. He has evaluated me and concluded that the gender dysphoria I experience is most likely the reason for my depressive periods, and I think he is right about that.
Before I knew I am a woman I was depressed without knowing WHY. Now I know and more importantly, these depressive periods are pretty rare and I know how to counter them by confirming my inner gender on the outside (read: dress sexy and apply beautiful makeup 🤗).
