Reflux help

Hello I'm a 20 year old guy. A while ago my stomach was feeling bad. Always going to the bathroom, constantly feeling dizzy like im gonna puke, a part of my mouth was really red from the inside and everytime I ate it or spoke it would hurt. Went to the first doctor said I should wait 2 weeks maybe it's a virus, kept me waiting for a month while on meds and a strict diet. Didn't work, went to another doctor, gave me pantoprazole, he said it isn't a virus but it's something called reflux, I didn't understand much , took a few days , recovered perfectly. 2 weeks later I'm feeling the same, spoke to him again , said to wait for a week and to keep taking panto. A week has passed still feeling the same. He asked for tests that I can't pay. He also said it could be anxiety, anyway the point of this post is to ask for advice on what I should do in my current circumstance. I've had a small history with mentally illness, had a few panic attacks when my mother died when I was 11. After a few years of therapy I recovered eventually. I've also had to take a pill for schizophrenia when I got older. Took em and now I'm normal there's nothing wrong with me. So my plan is to ask a pharmacist I know for what he recommends for anxiety. Take that and hope for the best. If those don't work then I'll ask for something else I could try related to reflux and see if anything works. Feeling like this for so long is very annoying, I hope someone can help.
