You really need to see a better class of physician, for starters. Wellbutrin is a stimulating antidepressant, not an anti-anxiety medication, and if you've never tried therapy going on these very strong brain-altering meds isn't a first step. And giving an antibotic just on the suspicion you have an ear infection, given the problem we have now with antibiotic resistance, well, this is how we got there. Most ear infections go away with no treatment at all, and here you've been put on one that kills off your beneficial flora that not only regulate the immune system and digestion but also mental health. You need to find better doctors who will look hard for a physiological cause without just giving you a drug to get you out of the office, and you would probably benefit by seeing a therapist who specializes in anxiety treatment because it's becoming a chronic problem and you don't want that, but you're not ready for meds at this point and that wouldn't be the one a good psychiatrist would put you on for anxiety anyway.
