Switching from Lexapro to Wellbutrin(Bupropion)… Withdrawal symptoms, and the addition of a new antidepressant.

Hi, I’d like to share my situation and hear what you think based on your own experiences. I’ve been taking 10 mg of Lexapro for about a year and a few months, and honestly, it’s really helped me manage my generalized anxiety and OCD. The problem is that it causes me to have vivid, intense dreams that really affect the quality of my sleep, and during the day I feel exhausted and very tired all the time. My doctor put me on a plan to reduce Lexapro to 5 mg for 4 days and then stop it to start Wellbutrin (Bupropion) 100 mg. It’s been difficult; I’m having some really bad symptoms: A strange sensation in my vision and body—it’s like a tingling in my vision and all over my body, as if I wanted to leave my body (I don’t know how to explain it; it’s very strange). I’ve felt more nervous and anxious, I’ve cried for no apparent reason (fun fact: I couldn’t cry while on Lexapro), and my emotions have been all over the place. It’s already day 5 of these changes. Oh, and the vivid dreams are still happening (though I don’t think they’ll go away quickly after just 5 days of the switch)... By the way, I also take 5 mg of Buspirone twice a day and Lamictal.
Let me know your thoughts and experiences—whether they’re similar or not... Am I okay? Is this normal or not? Thanks in advance!!
