When do you time your water drinking?

I was just diagnosed with gastritis a couple weeks ago I went to the hospital with really bad pain below my breast bone and ribcage they did tests and didn't find anything so they said I have gastritis also gerd they took almost every food I can think of away from me I am getting depression over this I have never felt so scared to eat ever in my life the agony and the waiting for the most excruciating pain it's terrible I hate it I'm only 25 years old and there's always something going wrong with me first my heart, ear infections tooth aches/nfection I get all that fixed and now this I don't know what to do I'm burping a whole whole lot after every consumptions of food and beverages such as water green tea but mainly water but after everything I get the urge to burp and when I do it doesn't feel like it's released anything I just wanna be healthy and normal again I want to eat I'm so hungry and so scared to eat anything even some healthy foods i can't have because of it I don't want any pain I just want help I'm tired of this and tired of crying I'm at my breaking point and also I have bad headachs and pressure in my head and that isn't helping with all of this
