This thread is such a complete heartbreaker. You seem like such a nice kid, and you don't even begin to deserve what's happened to your head. I'm 31, so I remember pretty vividly how impulsive and stupid I was when I was your age, and I couldn't be more grateful that I didn't have the money to pull a stunt like this. I waited until I was 29, which was still somewhat early for the transplant.
But here's the good news: you did something irretrievably stupid, and you're not going to do it again. While you did use 2,000 grafts, that's not a majority of your donor, and now you're on medications to halt/slow further loss. Something that no one on this thread has mentioned is that it's possible to have the grafts that this doctor placed excised and re-placed on your head--some doctors are very proficient at this. Given the atrocious placement and angulation of your grafts, it may make sense in a year or two for you to look for a procedure that doesn't remove any new grafts from the back of your head, but pulls up the existing grafts, re-places them in a denser, higher hairline, and fixes the crop-row placement and screwed-up angulation. That could go a long way towards mitigating the damage here.
But regardless of all of this, my thoughts are with you and I hope for the best for you.
