What Are The Withdrawal Symptoms Of Zoloft Tablets?

Does Zoloft withdrawals post to make you feeling crazy feelings in your head and body? I've been on Zoloft 100 mg a month and its making me feel so horrible! My doctor has put me on Lexapro but I can't even tell if its working because I have my Zoloft in my system. I'm 23 years old. All of the feelings I'm having in my head is making me think I'm going to have an Anueryism.
