Nervous about Wellbutrin XL

I was recently prescribed Wellbutrin for my ADHD and mild depression, but I also have severe anxiety and I’ve been seeing a lot of people say that it heightened their anxiety like crazy. Has anyone experienced anxiety with this medication? How can I deal with it or should I suggest taking a different medication to my doctor? She told me to give it 2 to 3 weeks to see if I would be OK, but I’m extremely nervous and I think I’m going to overthink myself into an anxiety attack.
