Controlling weight

Hi
I was a member just over a year ago and now I am back.
In July 2011 I found out I had a large liver tumour and I had 80% of my liver removed in September 2011. I returned back to work in February 2012. I put a lot of weight on in that time of having my liver tumour removed and was at my heaviest of 16st8lb. I soon lost a stone and half after stopping all the tripling of steroids etc. However, I am still at my heaviest of about 15st. It really gets me down, I'd love to be skinny. I can't stop eating chocolate and biscuits altogether and I suffer from low blood sugar so its swings and roundabouts. If I cut down too much I end up poorly with low blood sugar and then I have to eat more! I just can't win
. I'm also suffering from feeling tired a lot at the moment. Does anyone else suffer from any of the problems I have and am experiencing. I know I should think myself lucky after having a brain tumour and liver tumour but I just don't want to be 15st. I feel ashamed. However, Today I have just ate junk food and haven't even felt guilty lol.
Sorry for going on and on
