I Am Having An Anxiety Attack. I Think. I Am

I am having an anxiety attack. I think. I am sad, scared and joyless and anxious. I tale 80 celexa daily and 100 quetiapine at night. I took and extra 20 celexa because I felt more down and have been falling down more each day lately. My symptoms don't match serotonin syndrome. They actually are the same as most of the no serotonin syndromes. Can you help me? Can't believe you want money.
