Thank you for your response. It''s reassuring.
Don't feel guilty - if anything, it's a sign that you are at least somewhat healthy. Your body develops a tolerance to chemicals and medications over time, and antidepressants do eventually poop out. For now, the highest dose of wellbutrinXL works - in three or four years, maybe not - but it's OKAY...when that happens, you'll find another drug that will do just as well.
