i didn't wear one i'd be in constant distress due to hatred of my body so i figure that i'd rather be happy in presenting as male than be suicidal
Yes, but it's not always an either/or.
I don't have experience of transgender teenagers (well, not in my own kids, anyway) but we have - twice - been through the joys of CAMHS for suicidal ideation in teenagers, one through bullying, the other for more profound reasons based in OCD.
The second one may be the more relevant here. (Or I may be talking bollocks, but let's give it a whirl.)
In OCD, something can start from small, innocuous beginnings - for example, fear of bird flu for my child - and build to an obsessive pitch. At its worst, it spread to encompass all birds, however distant, all feathers, all mentions of the word even in books, and anyone who might have touched a bird.
He was happyish when avoiding birds and all mention of them. But avoiding doesn't cure this sort of thing, and instead it started to spread further to include other illnesses, poisonous chemicals, poisonous plants, you name it, and then the outside world in general.
The treatment wasn't to hide the thing that was troubling him and to forbid all mention of it. The treatment was to help him cope with it, by tiny degrees (such as a word on a page), and wait for the fear to reduce in intensity.
It's harder when the thing you fear is your own body, but honestly, I would be advising a child of mine to reduce the binding, a tiny amount at a time, while riding out the fear and seeing if it reduces in intensity.
In a very few cases, it seems likely that transitioning is the only option. But it's so drastic a measure that I think all other courses should be properly explored first.
(I'd probably remove the word bollocks when advising my own child, come to think of it.)
