Everyday occurence symptoms and conditions

My doctor prescribed seroquel to me for my severe anxiety. I took one b/f bed and woke up feeling horrible. I could barely get myself out of bed, I was foggy brained and lethargic. I thought it would pass so I went about my morning routine, when finally it hit me I couldn't take it any longer. And it resulted in a Full blown panic attack!!!! I took my clonazepam and eventually after sleeping for a bit, felt better.
I threw the pills in the garbage, I will NEVER take them again. I'm so scared to try anything new, b/c of what happened after taking seroquel. However I'm running out of options:(
