What is your experience going on sertraline and coming off it?

Hi I am currently 5 days into sertraline and haven’t had many side effects as of yet, I am just worried however when I do come to come off it will I be addicted? As in will I feel really anxious etc once I’m off and feel the need to go back on again? Or is it not an addictive drug? And what was your experience coming off sertraline. 

Also did anyone get any long term effects of sertraline, I have read about people getting PSSD etc , how common is that? Thanks
