Biaxin and meds

I was prescribed both Biaxin XL and Tussionex for acute bronchitis. At fist, the side effects were quite mild...drowsiness, "medicine head", some dizziness, however, as the treatment progressed, the side effects became much more severe...heavy sweating at night, insomnia, increased anxiety, depression. I thought I was losing my mind! I have a history of mild anxiety (one anxiety attack in my life due to being sleep deprived for 48 hours), however, during the course of this treatment, it seemed that I had experienced at least 4 or 5 panic/anxiety attacks at precisely the same time every day??? I have never been exposed to either hydrocodone nor a macrolide antibiotic, and have never experienced "mental" side effects from meds in my life.

Has anyone had further testing...allergy testing, blood work? I am going to be talking to my family physician soon, and really want answers. This experience scared the life out of me! Please let me know if anyone has had any viable answers for their ordeals.
