I think I might actually be able to help with the reincarnating thing. I myself have had similar thoughts. I imagine killing myself and being reborn as a girl and given the childhood I wish I had had. I also have had "crazier" thoughts. Like the idea that I could somehow trans-fare my consciousness into a female body (I was interested in the occult

)
Looking back on that last one I thinks it's absolutely crazy now. Sounds like something out of a comic book.

But desperation can unhinge even a most rational mind.
Right now I don't feel depressed I don't feel happy. I just feel "blank" I feel nothing.

I am hoping that HRT can sort this out.
The only thing I have found that really helps in any sort of way is finding "meaning" in the whole process. I myself try to think god has given me a purpose of some kind that involves ->-bleeped-<-.
But you can probably find a secular one too. Try altruism too. Maybe you could somehow help others who are in a similar position (Maybe become a therapist). Happiness is like jam you cannot spread it around without getting some on yourself.

But these may be unhealthy coping mechanisms that someone as unhappy as you has devised so I am not sure whether this is advice you should take.
PS: On a separate note I am actually in the age group that some people on here have labeled as the "live fast die young squad". I am 20 and this describes my mind set to a large degree, I have thought about taking up heavy smoking (I am currently a nonsmoker) deliberately to die quicker.....which is very sad.
