A few weeks ago I started experiencing small panic attacks during the day and a higher level of anxiety. It became so severe one night one of the attacks woke me up in the middle of the night. I have also consumed second hand marajuana smoke and a small amount of alcohol over the course of about three months. What could be causing these symptoms? When the panic attacks occur I lose control of everything including my sight and ability to stand up straight. Im terrified and I dont want another hospitalization. This didn't start occuring until I was put on zoloft, so im guessing that may be it? I would appreciate some advice. Thank you.
