Hey Toto, I'm sorry to hear about your experiences and I give all the hope to your future recovery. I myself am an over achiever, and as my GCSEs were approaching in year 10 of school, I ended up going through anorexia, dropping to 4 stone 9 pounds. It was so horrible, I was taken into an adolscent mental health unit and treated there for 8 months, where I made a full recovery. It is achievable my friend, I sat my GCSEs in there, and came out with Bs and a few As but many Cs, getting me into college. I realised then that even though I had been troubled and didn't get the A*s that I wanted, I was still acceptable to top colleges, and now they know my illness, I have a higher oppurtunity to get into universities of my choice. Recovering a mental health issue is the hardest thing possible, and probably THE most achievable thing I have ever done. I am so proud of myself. I weigh something around 10stone now, I'm not overweight, but I am a bit chubby (I think I am) but hey, I love my life. Once you 'fail' or don't achieve something, just think, you're recovering/recovered an eating disorder. Probably the best thing you would have ever done and impossible for others.
I wish you the best, Fay xx
