Thanks for the replies guys. I've had bouts of this since I was about 13 and I'm now nearly 20. My doctor told me to try something to regulate stomach/oesophagus contractions but i can't remember what it was called now! I'll find out when i see her in a week but if anyone knows what I'm on about it would be good...

@Miswimmy - nobody is pressuring me apart from myself. I used to get teased for being skinny as a kid and now I feel unattractive when I'm skinnier.Also, my boyfriend was concerned I'd lose weight and i don't want him to stop finding me attractive because my boobs and bum are disappearing :/
