Zoloft withdrawal or no ?

Im 17 was taking Zoloft for a year and a half for ptsd which is was for depression and anxiety . ive always had depersonalize how ever you say it which i feel like everything is unreal or im in a dream for some time now and ive learn to deal with it i started at 25 and went up to 75 i decided i was feeling better and that i didnt need the pills anymore so the doctor gave me instructions on how to stop we went down to 50 mg to see if i would do good i did well and didnt notice anything so i went to 25 mg for 2weeks then went to half of 25mg the next two weeks and then stop . i didnt notice anything which was the week of Christmas when i quit completely during that time i lost a grandmother the 28 of dec and a great grandmother jan 15 but i didnt notice depression so i haven't had nothing happen until these past 2 weeks which ive been off zoloft for 5 weeks or maybe 6 weeks but would i be going through withdrawal symptoms this late ? im experiencing slight depression i cry for no reason sometimes , i started to have bad feelings like something bad was going to happen nothing like suicidal thought just like i feel like something gonna happen to me . then i started having headaches i have a cold right now so i thought it could be sinus headaches . but the past 3 days ive been feeling like im having panic attacks like something bad is gonna happen again it got bad last night and i finally fell asleep. now im still feeling like that and now i can remember stuff kinda but i kinda feel like im in a brain fog ? or my brain is numb i cant focus on what people are telling me , its like its shut down . i have contacted my doctor and i cant see her till the 6 of feb. but i just need some answers and to know if this is gonna get worse i dont wanna go back on medicine but i dont know whats going on .
