I have had depression for several years now and recently I have not taken my medication for my depression for a very long time 100mg Zoloft. I decided to start taking it again because I started getting sweaty and shacking or afraid to be alone and causing stress in my marriage. So I took it that night I got up to go to the bathroom and had diarrhea and started getting a tingling hot burning inside starting in my spine and going all over and I got dizzy light headed now day 4 and I feel fine till all a sudden I get a tingling warm feeling then I start to shake and get so worked up my belly is upset or in knots till I calm myself down . So is this a flu virus or anxiety? Am I going crazy plz help . Am I the only one ?
