Stomach issues....constant nausea n dizziness

Okay lately I've been feeling full, constantly dizzy and nauseous for 2 or 3 weeks and haven't been hungry in at all. I wake up in the morning feel full until after I eat something then wish I hadn't ate because I my stomach start feeling weird and gurgles... And on top of that i feel like I'm going to vomit.... Sadly I'm afraid to so...most times I just try and go to the bathroom or take an indigestion pill. Then after awhile my stomach start to burn....like feel hot food churning inside...my stomach starts hurting...strong nausea..my face and neck get really tight...n I feel over heated. (I start to panic when that happen bc of the vomit thing) but usually it'll come up as acid reflux or baby burfs. I've no clue whats going on with me, although I've suppose to have been taking reglan and seen the dr. But my mom is too lazy to get my pills and take me. So whatever is making sick is anonymous, and I can really use some help or any suggestions plz Also I've been having killer headaches, and took a half of Bc or sometime Tylenol for it but one them cause me to bleed a lot (3 days) when I go to the bathroom so I can't take them anymore Additional info if it helps: I'm 16 and still in high school and been missing a lot of days because I've been feeling like this non stopped. So before school I try and take a Dramamine to get rid of my nausea and vomit feeling. Although I've been a little strug out as well about school, n my diet and stuff. And have lost a few pounds.
