constant nausea and hunger?

[anongurl000]

Hello.
I am a 19 year old girl. I don't smoke or drink, I have fast metabolism though which causes me not to be able to gain weight, so i've always been eating a lot without really caring about what I eat. I don't work out, never have. I've never had any problems with my health.

Since around September last year I have been suffering from what I suppose is heartburn or acid reflux. I feel a burning sensation or bloating in my stomach, bloating in chest area and sometimes nausea to the point where I have been sitting in school considering taking the rest of the day off because of the pain. That only ever happens when i'm at school though, that it gets that bad.
I quit drinking coffee a month ago and switched to tea (i've been drinking coffee since I was 5 years old!) and I have almost completely quit eating candy and snacks and switched to healthier "snacks" such as almonds and dried fruits. It's done a bit difference but not much (basically it doesn't matter what I eat because it makes no difference). I saw a doctor when all this started but for a different reason, it was for one of my very intense period cramps that caused me so much pain I went to the ER. They scanned my stomached (made an ultrasound) and found nothing. I heard the doctors mention something about the gallbladder without bringing it up to me - I didn't ask, stupidly enough. They prescribed me omeprazole but I haven't taken it yet because my mother had some reactions from it when she ate it. I don't wanna take risks.
Apart from the bloating and burning in my stomach I am CONSTANTLY hungry which is such a dilemma because eating makes my stomach worse. I can't even eat some sandwiches or something really light and I don't feel excited about eating anymore because I am afraid it will hurt. But I still eat of course, but it's no fun.

I called a doctor but they said I need a full checkup which will take WEEKS to find time for so I can't do much right now, just live with it until I can find out exactly what it is. I have a theory stress and anxiety could have triggered it though rather than anything else. I am very sensitive to stress and lately i've had lots of negative things happening in my life, and I am about to graduate as well so I need to know what to do with my life RIGHT NOW and everything that's happened in my life has been distracting me from planning my future and it was during all this my stomach got like this and I was sick a lot and home from school many times throughout the autumn, weeks at a time and I wish I could just at least grab a cup of coffee and relax but I can't even do that anymore I suppose because caffiene is "bad" for you.

I don't know what to do? Any advice? I just want to be able to eat and drink coffee and not worry about everything anymore. I'm so sick of this, how do I make it go away?
