Cold-turkey quitting Zoloft/Sertraline

I began taking Zoloft over a year ago and it helped me a lot.

I've stopped functioning very well (lazy) so I want to stop taking it because I think this lack of anxiety is making me complacent with my situation when I deserve (and should be) more stressed.

I don't feel strong emotion and lack interest in living a proper life, which is different from how I used to be. I had more willpower to study and go out and talk, whereas now I just don't care at all. I cry relatively often.

I've never had side effects, so can I hope for no withdrawal symptoms? I don't care to wait for my psychiatrist's opinion on this.
