Hi there, My anxiety attack was triggered by marijuana (was my first try and my last) back in January 2014. After that day, I had panic attacks numerous times with in the 5 months and I went to ER many times thinking i m having some serious problem and kind of sure that I was dying. Since that specific day, I don t feel my self. I feel different. I ve this confusion that don t go away. blurry vision most of the time. dizziness and lightheadedness most of the time. My doc diagnosed me with anxiety and I m taking Celexa and Xanax as needed basis if I feel the anxiety attack. What still confused me is I m a normal happy guy (NO MEDICAL HISTORY BEFORE) and could t accept the idea that I have anxiety problem. I am not sure if the marijuana can cause anxiety from no where! At this time, I m just more confused about my situation since I lost my job 5 months ago due to this problem and is still debilitating my life. Sorry if I have some grammatical errors since I ve been in the U.S for few years & of course English is my second language. ANY INFORMATION IS VERY HELPFUL TO ME. PLEASE HELP, I M IN A SMALL HELL.
