Hi, I've been having stomach pain for almost three months or more. I thought I'm just feeling bloated because I'm getting my period but then the pain gradually gets worse and worse. I've lost appetite and if I do eat, I will eat at a little portion and doesn't feel full. Three weeks ago I suffered a nausea and everytime I eat I tend to throw up. On the other hand I've also had sleeping deprived for a year now, I would wake up in the middle of the night every one hour or two hours than stay awake for an hour or more, and not to feel tired in the middle of the day. At the moment I'm feeling really sick, my stomach stings and I could not breathe properly earlier. Everytime I breathe my head hurts. Also lately I've been burping each time I get up from my bed and it's horrible.
