I'm glad that you've seen a gastroenterologist and are on medication.
I almost wish that you would see a psychiatrist rather than an internist for your emotional and anxiety worries. These specialists are so up to date on all the newest medications and will know exactly which ones are best to treat your particular needs.
A good internist is going to recommend that you see a specialist, frankly, because they recognize that you may need to talk about some things with a specialist that you don't feel free enough to discuss with an internist, who, incidentally, doesn't have all the latest about the newest medications for emotional illness because that isn't their specialty. Oh, they can treat simple depression, but you may have something else going on that needs attention.
Keep us posted and good wishes,
