Im 19 and just graduated HS..About almsot a year ago i sufferd 2 panic attacks caused by Aderall the Drug..I was perscribed to Effexor after beacuse I was having bad anxiety issues..Well i learned that effexor is a very bad medication it was making me go crazy so after about 4 monthes I stopped.. Well sense going off the effexor Ive noticed my body seems to be shutting down. All in the past 8 monthes sense getting of the effexor Ive gained 40 pounds, My eyes will never stop dialating there constanly going big to small big to small every 5 seconds, I now have huge black spots all the way around my eyes, Heart Palpations sometime , I get brain shiver that start at my neck and either go up into my brain or all the way down my back, I still feel some mild anxiety and I feel that things just aren't right.. Any advice on if I should see a doctor or what I need help.
