Need some advice on reflux and gastritis

Trying to figure out why I'm having gastritis again. I have low stomach acid and used to be able to take 6 650 mg of betaine hcl per meal. I also take armour thyroid. I began reducing the number of acid pills in late January, because I felt I needed to, but eventually I started to feel worse early April, the doctor decided to take me off my thyroid because we thought I no longer needed it. At this point I was taking 2 to 3 hcl, but after going off the thyroid I am no longer able to tolerate any acid pills. I am now back on the thyroid,and am trying to heal my stomach so I can take the hcl again. I've been taking gastrazyme, dgl, glutamine, slippery elm, marshmallow root, since may 1st and I still cant tolerate any acid, and I very much need it as my weight went from 100 to 90, (100 is healthy for me, I am a petite female) and I'm losing a lot of hair and just feeling like crap. If anything my stomach is worse and I have an ache, and a soar throat every morning from what I assume is acid reflux. Currently I eat eggs for breakfast, and a combo of chicken or fish with vegetables for lunch and dinner. I eat at least 3 bananas a day and avocadoes and raw honey. I take peppermint oil 3x a day, 3g of glutamine, 4 gastrazyme before each meal,2 bio hpf before each meal, 3 tabs of DGL, and I also drink aloe Vera juice. I have been tested for h pylori and it was negative. I know I need to cleanse but I cant handle the die off while my body is deficient from not taking stomach acid. I just cant figure out why my gastritis is worse after taking all these healing supplements.
