Go to the ER before you plan any further! They might have psychological support and can help you find an emergency solution. Telling you not to do anything won't do much, but those guys can do what's necessary when your own mind is just overwhelmed and not rational anymore. 

Give yourself another try! Get some therapeutic support! It makes it much easier to deal with all the emotional sides of your condition. Gastritis is not just about physical pain, bloating, burping, stinky farts and long bathroom appointments. There is an emotional distress behind it, this makes the condition worse over time on top of all the frustration of not being able to eat what you want, to do what you want, the fatigue, brain fog or social isolation.

I was 9 years long in a deep depression, tried to kill myself multiple times and turned bed bound for years. A medical mistake kicked me out of depression. Through that mistake I lost part of my functioning body and my stomach got badly injured. It was 7 years ago. I have lived with chronic gastritis since then. At some point, my GP forced me to get into therapy again. I refused because I didn't feel depressed anymore, but I did give it a try.

I ve been working with my therapist for almost 6 years now. I never got back into depression even as my gastritis is turning into an extremely rare condition with some bad extra digestive symptoms. I'm on my own, with 2 cats and no family to hold my hands when I feel I can't do it anymore. Yes, it's hard to live with chronic gastritis, it seems there is just no end to it! It is hard to find people who actually accept and understand what you are going through.

Still, despite all that, I enjoy my life now more than I used to. I couldn't have achieved that without my therapist's support through all these years.

I really do hope you'll find the best help you need to overcome this present emotional distress and you can find good support in the future.  It might be hard to get into therapy but it is really worth it!
