Thanks everyone x. I do still go out, in fact I work part time (sedentary job!) but my mobility has got quite a bit worse in last couple of years. It is all a bit of a vicious circle, I put on more weight and have noticed some people don't talk to me so much, probably in my mind, but hard to make friends. being with people makes me happy and I don't then turn to food.
I don't have many friends, and no family close, not a great marriage, so I eat!! I have recently gone to a WI once, and must make the effort to continue it. I will retire in next 2 or 3 years so want to make a bit more social life for myself.
Thanks for the suggestions Rosanna, I'll look at the books. Not sure about Lighter Life.
What I have found useful in past has been My Fitness Pal - as logging all food and weighing regularly is helpful.
I feel the only way to get under control is to be shut away and forced to eat properly and exercise, but then eventually I'd still have to face things when I came out, so that isn't an answer.
It is hard to justify how I act. Everything I say sounds like excuses, which is true. I just wanted people to realise it isn't as easy as you might think, for some of us.
