When will this end

I have been dealing with Symptoms since end of july/early August. i had an Endoscopy in Novemeber that showed i had Gastritis and Hpylori. i have lost a total of 39lbs since begining of September. i am 8 weeks post treatment for Hpylori but have not retested yet. i am still having the following symptoms.

Lack/loss of appetite(i can eat but i dont have the urge)

Bowel inconsistency

Lower abdomen pain mostly on left side

upper stomach discomfort/buring feeling

sometimes fatigue

i feel of balance a bit at points

sometime left side pain on side of body that goes to the flank area.

anybody else dealing with this after a while? im really getting stressed and anxious about it.
