Neurological and stool color

Recently got diagnosed with gastritis after having endoscopy.

It all started after having silk milk in June of last year and had a terrible episode for a couple weeks having constant nausea, bad bloating, no appetite, fatigue, pain in lower back and shoulders, bad acid reflux and heartburn. Ending up not being able to eat hardly anything and losing about 15 lbs in a week and half.

Doc put me on omeprazole and had terrible neurological side facets from it then got put on famoditine and didn’t feel like it was working so I stopped taking it.

Mind u I never had any Gerd or gastritis symptoms before until that one night. What could have caused it all the sudden?

Fast forward I was having panic attacks nightly in august-December of last year which made me go into constant derealization and dissociation and depression because I had gastritis and panic attacks and none of this was known until lasted and I had no clue if I was dying or not. Now I’m trying to get out of the constant derealization and existential anxiety.

Fast forward to now I have some anxiety mostly existential and heartburn everyday. And brain fog. I also have tension headache often and have this weird feeling in my eyes like there’s pressure behind them and they just have a really weird feeling.

Eye feeling kinda also feels like there being pushed out from the inside or they strained or trying to cross each other or something.

My stool color seems to be pale ish yellow or very light brown almost constantly. Could this be from gastritis or a gluten or dairy sensitivity?

Could it be a food allergy causing these symptoms or just anxiety or gastritis? At points I feel like it could maybe be a gluten sensitivity but it all started with dairy.

So now I’m trying to figure out if my weird eye feeling and tension headaches and anxiety has something to do with a food sensitivity or allergy or if it’s from gastritis or something completely different. Just asking and looking for some advice or insight on my situation. Not looking for any diagnosis just some insight or possible ideas.

Main issue trying to get resolved is my stool color and the eye weird feeling sensation.
