confused: do I have GERD gastritis or LPR?

My stomach has been bothering me since Jan12. My doctor told me I probably have gastritis & put me on Zantac 150 2x a day for the next 3 weeks. My symptoms: -stomach gets noticeably more unsettled when lying down. -sometimes stomach pain in but it is mostly a feeling of constant "butterflies" or a heavy unsettled stomach. -burping very often -taste of food in my mouth that I ate hours ago even the next morning -lots of saliva have to swallow a lot when I'm trying to sleep minor feeling in throat Since starting on the Zantac (it's only been 3-4 days) I've noticed that my stomach just feels way worse. I feel heavy and icky very tired BUT I feel a lot better when lying down. In general however when I'm up and about I just feel bad. The moment I sit up in the morning I get a weird feeling in my stomach. I'm still burping a lot. I've noticed that food seems to be affecting me more and I didn't really notice a correlation between what I ate and how I felt before the Zantac. I've had Eustachian Tube Dysfunction for about 10 months now. I'm starting to wonder if I have TMJ as well which might explain these digestive problems since apparently it's linked with LPR. Also my chest has felt consistently heavy sometimes a jabbing pain on the left side since about December. This might be due to a blow I received and the fact that I've been blowing my nose constantly (valsalva maneuver) to relieve my ETD. My doctor says it's probably costochondritis - not a GERD symptom. I've also started having panic attacks since December but I think I've got it under control by breathing through them. I've done 2 EKGs & appear fine. Finally there is a major history of diffuse gastric cancer (from age 27) in my family. I'm 22. I haven't had any heartburn. I am confused. What's wrong with me? Am I treating it correctly by taking the Zantac? Are the side effects normal? I know GERD LPR etc can occur concurrently but what are all my symptoms indicative of?
