Support with gaining weight wanted.

Hi all, my TMS has led to a diagnosis of gastritis, sliding hiatal hernia, chronic constipation— with gas throughout my intestines and bad bloating. I developed a fear of food, and indigestion so bad I could barely eat. I’m eating a bit more these days, but still no appetite, I’m anxious to get that appetite back. I am 5‘7“ and have gone from 132 pounds to 101 pounds. I’m a bag of bones. Would love to hear from anyone else who dealt with this, or just some cheerleading from anybody who succeeded in finally started gaining weight.
