I have a jelly tummy post-babies. I'm not going to bother too much about it - I still have great legs!
Please get some help with your eating. Throwing up is fantastically dangerous and because of the electrolyte imbalances it causes, you could have a heart attack, amongst other things.
One of the horrible problems with eating disorders is that what, to normal people is completely mad, becomes so normal.
I had a horrible time with food for about 16 years, and for the first five, I really was on my own. I tried very hard to deal with it by myself, and was so unhappy. It is a horrible illness, and the sooner you can start to deal with it, the better the outcome.
There are lots of people on here with similar issues past and present, so keep posting
My own problems were less to do with being fat and more to do with being there at all
