autoimmune atrophic gastritis, will I ever be able to live life again

Hello everyone! I am a 23-year-old female who just got diagnosed recently with autoimmune atrophic gastritis. I had an endoscopy done about a month and a half ago and with the biopsies and follow up bloodwork we found out that I had AAG, I was very confused about my condition because my doctor was not telling me clearly exactly what was going on, so I had gone to a different G.I. doctor to get the reading on the results and he told me that it was AAG and that it was pre-cancerous. as you can imagine I heard this information in shock and I think I cried for three days straight. Realizing that stress causes more flareups and that I need to take a step back and breathe. From the blood work, we found out that I had high gastrin levels and pernicious anemia.

Symptoms - Chest pain that radiates to my back - Left side pain under my ribs - Anxiety - Constipation - Irregular bowel movements, irregular stools. - Acid reflex that causes irritation in my throat. - Stomach pain - Brain fog - Tiredness, low energy

What am I doing currently. So currently, I’m taking omeprazole once a day 40. And I’ve completely changed my diet, which has not been an easy journey.

avoid: - spicy - Acidic - Fried - Caffeine - Gluten - dairy -Smoking - drinking - red meat - eating out - overly stressing - Google lol

I pretty much eat bland food with Barry, light salt and pepper. I ordered a book on Amazon for gastritis which has been very helpful for food.

What do I plan on doing?
Well, I will start with. I have spoken to a functional coach through Silverfern brand. I’ve had a consultation so far and I plan on doing their protocol. I also have a colonoscopy and follow up endoscopy tomorrow. So once I get the results from those, I will review them and continue further testing with my G.I. doctor to figure out the root cause. I also have appointments lined up for transfusions. I am starting to take B12 shots which has been a game changer for my energy levels.

That being said if anybody else is going to something similar, please advise even though I feel like I have a very good game plan on how I want to move further I still have days where I feel stuck and feel like I am going to die of cancer very harsh, but I don’t know how to get over the anxiety. It’s taking a toll on my mental health. I feel like I have no social life so please give me any type of advice that you have. I just wanna know if I will ever be able to live life the way I used to before. Will I ever heal?
