Anorexia & Gallbladder Disease?

I went to the doctor’s yesterday for a constant bloating feeling in my upper stomach, ive had a endoscopy done and theres no signs of any ulcers or anything wrong with my stomach. Im 20. I had my son at 16 and my daughter at 19. Ive had Diagnosed Anorexia for about 4 years. Also, Ive had constipation problems so bad my intestine Collapsed (rectocele) What i feel now is, a constant feeling of bloat in my upper stomach (right between my ribs) feeling like its pushing on my diaphram and i can’t breathe. Like a knot in there kind of, sometimes when i eat i feel like I can’t swallow cause theres something stuck in my throat. It’s not Anxiety, im on Ativan daily already. i don’t think im having full blown Gallbladder Attacks but i have had it where after i eat my entire chest hurts, ive gone to the ER numerous times cause i thought i was having a heart attack. Any Information or Opinions would be appreciated. Am I at a higher risk for Gallbladder problems? i also have had a Hormonal Imbalance since having my daughter a year ago and did Hormone Replacement Therapy. Anyways, Anything? lol Thanks
Also wanted to Add, Ive had horrible nausea, and Dizziness since this all started.
