New story symptoms and conditions

I was given levaquin 500 mg 6 days ago for phlebitis. Since I started I have had terrible anxiety, panic attacks, fear of dying, nightmares, crying jags, and very sore neck and shoulders. I called my doctor today and asked about the side effects of this medicine. I am NOT going to finish my 10 day dosage. I'm done. I've never been so miserable. This is strange because all this past summer I took low-dose levaquin, 250 mg 4 days a week because I have bartonellosis, a co-infection of Lyme disease. It didn't bother me beyond some leg pain then, but now it's a whole new story. I am TERRIFIED of this antibiotic and modern Western medicine in general.
