I am a 30 year old female, overweight. My anxiety started back in March 2010 when I lost a pregnancy at 20 weeks. Just this past November I had another misscarraige but around 5 weeks or so. I am very uptight, I used to be on fluoxetine but had to get off because of pregnancies. I am currently taking Wellbutrin SR. Recently I have noticed that my left arm feels funny from the shoulder blade down. Plus, if I elevate my left hand, it seems to shake. I am a smoker but not heavily. Maybe 1 pack per 3-4 days. Every once in awhile i have also noticed that I get slightly dizzy if i move my eyes too fast. Because these symptoms are happening, it sends me into panic mode even more. What could be causing these issues?
