You have nothing to be ashamed of, our culture teaches us there is only one way to be, but that's just not true and never has been true.

Stigmas about mental illness ARE stupid. I've had several people say remarkably ignorant things to me and I've lost friends over it because I came to a place where I wasn't willing to tolerate their put downs, intentional or not. I've also lost people who felt that I was "too negative" instead of being able to deal with me being depressed. My life is richer now that I have been able to surround myself with a few people who are willing to at least try to understand and give me the space to work on my problems.

I've got scars too and most people don't know about them. I don't talk about my gender or body dysphoria, not even with my therapist. For now it's something I'm working out on my own, mostly because I have more immediate and paralyzing problems like depression and anxiety. Unless you have a plan to harm yourself or someone else, your therapist is ethically not allowed to talk about what you say without your permission.

I've had the dysphoria nearly all my life and I've hidden it and been in denial about it most of my life. The body dysphoria is still just as bad but the gender dysphoria is getting better as I learn to accept it and figure out how to, and how much to, express it.

The most important thing is to take care of yourself and get the help you need to be ok. Taking the first step to talk to a therapist takes courage. Asking for help takes courage. Be proud of yourself for getting that far even if you feel driven to it. I hope your father is supportive! If it seems like he is, try to talk to him at least about the depression.
