Just saw your post and it sent shivers down my spine... take a look at my story, maybe it will provide some insight to dealing with this type of thing.
The only thing I will say is this... HT's aren't garunteed. If you do get one, you can experience shcok loss around the donor site and then that scar, that you paid money to put there, will be visable. Just a thought... your a beautiful girl, I know being younger makes these things harder to deal with... but think about the long term or the possible things that could go wrong. Fixing one thing might lead to creating another. No one can promise you it wont.
