Azithromycin 5 Day Dose Pack and medication

My Doctor prescribed this medicine to me for an ear infection and I had the worst anxiety attack last night. It woke me up at about 11pm and I thought I was dying. I had to get up and walk around outside and have my mom walk me through it. I have had anxiety attacks in the past, but for some reason as soon as I started taking this anti-biotic I noticed them coming back. Symptoms were shortness of breath, fear of dying, feelings of having a heart attack.
The best advice I can give is when you start to feel this come on...
Get up and go outside, and walk. Move your arms around and shake your hands. Also keep in mind that this is just an anxiety attack and your not going to die.
Some people are just really sensitive to medication. I am one of them.

I felt like i was going to die! I paced back and forth like a restless tiger in a cage, nervous, panicky, jittery, and restless. I felt like I was choking on flem and I was ready to go to the hospital! As for sleep ...good luck with that. I finally fell asleep at 3:30 AM and was up by 6:30 AM! This has been going on for two days now. I called my Doctor and he said that he has prescribed this medication to thousands of patients and never has heard of a reaction like this. My doctor told me to stay off of the meds for two days to see how I feel. I'm afraid to take these meds or anything else again.
