I have been recovered from anorexia for 2 years now, and whilst I would still say I wasnt a severe case (my BMI at my lowest was 16.5, and I was never an inpatient) I know what you are going through.
The thing that pushed me into realising that there was something wrong and I needed to recover was when I saw my dad cry, he never cries. and that was when I realised that I was affecting people other than myself.
The first 6 months of recovery were hard, and I had to take it step by step slowly eating more, trying to ensure I resisted the urge to both undereat and overeat. Over time it does become easier. Whenever I felt like I wanted to go on a losing weight regime again, I tried to remember all the bad things, the adverse effect on my family, the days of depression and crying, the hours spent in the bath just trying to get warm, the times when I would brush my hair and it would come out, realising the possibility of not being able to have children. When I remember these things it helps me to realise that its not worth it. Nothing is worth that.
I'm now a healthy weight (9st, 5ft 5) and whilst in perfect world I would drop half a stone, I realise that it is a slippery slope, and even now, 2 years on, if I try to diet I know it could be a quick path back to where I was, and that's not really what I want or who I am anymore, there's more to life than that.
I'm not sure if any of that helps. I hope it does.
