Stomach Problems?

the symptoms i have been dealing with for 7 years, early it started with a stabbing pain and felt worse when i moved or pushed in on my stomach, the only way to take away the sharp pains is to lay on my back for awhile, it started to come more frequent, 2 times i got discomfort for a straight week, now im getting morning discomfort, its like pressure on my stomach, feels worse when taking heavy breaths, once i sit up it slowly fades. I'm also 19, and male if that helps. frequent gas and burps, too much food makes me bloated, anxiety that can work myself to getting a stomach ache, when i swallow u can hear the weird sound in my stomach when laying down. thanks, I'm also a slight hypochondriac, mostly when i was youngster, but it had to do with a lymp not on my kneww which i feared was cancer and sitting on the toilet after it was cleaned with cleaner and stuff like that:P
