I'm a 15 year old female and I've spent 8 months in constant pain. It began when I would eat a meal and feel a bit sick after it, I didn't think much of it as I thought it was some sort of stomach bug. But it never stopped. I talked to my parents and they just said, "stop eating unhealthy food", which is a reasonable thing to say, so I cut out a fair bit. It helped for a little while but it came back again. I kind of dealt with it for the longest of time, not thinking anything bad was really happening even though I wouldn't dare move incase I'd throw up. I'm not afraid of vomiting, I just prefer not to. I recently decided to track what I was eating and see what was upsetting me, it turns out my hot chocolate and milk in cereal daily was a big factor contributing to it. I cut that out for a while and notice some improvements, but then if I'd eat certain meats I'd feel sick as well. I never really did lose my appetite until recently and I struggle to eat daily. If I do eat, it's just plain bread, or toast with butter, that's the only food I can trust. I thought maybe I'm lactose intolerant, but I obviously can't self diagnose myself. I've lost a lot of sleep from it and I definitely don't think that's helping. I'm not anxious or depressed, well from what I know I don't think so. I deal with it by laying in bed, sitting up and burping. If I try to have a nap, I generally wake up much worse. It depends on how it lasts during the day, but this morning, 7am, I decided to have cereal and I've been queasy all day, it's now 5pm. 

To sum it all up, eating too much (a normal amount for an average being), having milk and having some types of meat (chicken is a main thing I've noticed), all make me feel sick. When I feel sick, I feel as if I need to hang around the toilet just incase, I feel queasy and nauseous and I'm always very uncomfortable. The best way I deal with it is burping and that generally helps quite a lot. I've lost my appetite and I find it hard to sleep if I've had dinner. No mental illnesses, nothing traumatic or stressful in my life, but it's been lasting for 8 months and I want it to end!

If you have any suggestions of what it could be, please let me know, I'm desperate to have my life back! 

(If it sounds very repetitive and not coherent, it's because I'm extremely exhausted and disorientated from staying up all night for the past three days.)
