Hi Doctor! I Have Some Stomach Issues For A Long

Hi doctor! I have some stomach issues for a long time! I saw doctor almost 8 month ago amd he did endoscopy test , which showed that i have bad erosion, signs of getting ulcer, i did have small ulcer but it got closed itself! Got prescription and drunk several medication! And kept diet! But nothing helped me so far! And i started drinking pepsid famotidine couple days ago, which was giving me pains in my stomack, so i changed it to nexium 20 ml, but i today when i went to work i felt i am gonna pass out the moment i enter the departement store! I feel so dizzy and i am like in the air! Plus stomach acid never lets me alone! I was feeling i am gonna pass out, didnt have any control on my body! Any help???
