Oh I can relate to every single word of what you just said. I put all my weight back on within months and even though I knew the food wood make me out weight in I just couldn't stop myself.
When I was at my lowest (9st 2lb) i bought some super skinny jeans from topshop, I don't think I would even be able to get my ankle I'm them at the moment. I still kick myself now and can't believe I ate my way back though 2st 11.5lbs after all the hard work I put it
I think (said in a very quiet voice) that I have got my head back in the right place... We CAN do this!
Good luck for weigh in x
