So, I started writing a (very) long answer with lots of detail, to respectfully and honestly answer your questions, from the PoV of a non-trans person that did quite a bit of research, but I stopped.

I just can't. Neither can I be respectful towards you anymore. Your constant misuse of the term "mental illness" is aggravating, and quite frankly, disturbing. To the point I am wondering if it isn't, in fact, a cry for help.

Are you mentally ill? Do you need help? It would really seem that you do.

Just as a thought to ponder: when most other people are mentally ill, maybe you should consider seeing a shrink.

I also want to correct a few things, not for the user I'm answering to, but for anyone reading my comment, because I just can't let such a heap of manure stand uncorrected:

1. There is no such thing as "physical gender". Gender is a coercion and domination religious tool.
2. Being trans, or identifying as a different gender, is a means to escape religious shackles. Escaping religious shackles isn't "mental illness".
3. "Mental abnormalities" are bullshit. We aren't computers, we are humans, and all different. There is no normal, except maybe the norm that most dimwitted people have no issue with LARPing a bullshit character decided for them, their entire life...
4. Comparing "AD(H)D, BPD, Schizophrenia, etc" is exactly like comparing "bud light, meth, crack, etc". I know that on the post-2015-internet people talk mostly out of their asses, but that doesn't make it ok.
5. Dysmorphia is a mental disorder. Dysphoria is "acute anxiety". Again with the mental disorder implication.
6. Force feeding medication to alleged "mentally sick" people is a nazi method. A humane approach is to provide care. As in talking with them, listening to them, helping realize, overcome traumas, (re)constructing an identity, etc.
7. Feeling uneasy with one's body is common, it is caused by the image communicated by society about what a "desirable body" is, and the difference between that image and one's body.
8. Medical and psychological care aren't opposed, nor they are opposable.
