Help! Am I still having Withdraws?

Alright here the thing. I was 4 years of age and I was diagnosed with Turets or however u spell the random F**** you thing. Yes I know. I have lived with it my whole life untill my Junior Year of High School in a Varsity Football game I get to that. I was 12 years old and I was given a medicine it is a downer (sleeping med) called Seraquel. I was on it till I was 17. I'm still currently 17 but I turn 18 in 3 months. I myself wanted to go into the Army and I have played Football for 8 years Baseball for 12 and Wrestled for 2 years. Thing is I quit Cold-Turkey. My mom was a nurse b/4 she got disabled which she tried wheening me off it. At 12 I was taking 25mg which I promise you could knock the hell out of anyone here. at 15 I was on 100mg. 125mg then back down to 100. Late November we were in Gulf Shores playing them just as a filler game. We stayed up there our whole Fall Break. That time I went completely off of it. I was going through the worst days of my life. No energy to play the football game. I had tremors cold and hot flashes no energy throwing up you name it i had it. Last Night I was really stressed out over some stuff but I guess my body wanted it. At this very moment as im typing this to you it feels like im going through the withdraws again. I can handle pain but not this. Someone please tell me what to do.
