I was prescribed Wellbutrin for anxiety, and because Lexapro had been taking away my ability to orgasm. I feel genuinely stupid. I had a brain injury 8 months ago which caused issues, but everything is worse now. I can no longer speak to people without feeling confused or detached. I now orgasm within a minute, I lose my train of thought within seconds of starting a sentence, I can't face situations that require genuine thought. I've been on for about a month now, at 100 mg. What do I do?
