Can anxiety cause recurrent gastritis? What alcoholic drinks are least likely to trigger stomach irritation? I already take omeprazole.

None. Alcohol is . alcohol. You have reasons not to drink alcohol: 1) It worsens chronic gastritis &/or gastroesophageal reflux. 2) It worsens depression. 3) It interacts with Fluoxetine to cause dizziness, drowsiness, difficulty concentrating & impairment in thinking & judgment. Ask your GP to refer you to a psychiatrist & a psychologist for accurate diagnoses, therapy & medications, & to a gastroenterologist. .
