I gained like 14 lbs around 2 years ago, then I started making myself sick after lunch at work, then I started using laxatives and being obsessed by weight
and counting calories. I lost the weight
I gained and for the last year have maintained my normal weight of 124lbs, at 5 ft 5 that's perfectly healthy.
I no longer purge, or take laxatives, yet after every time I eat I just want to go and puke.
