Zoloft and irritability??

Hello I just started Zoloft for my postpartum depression and the first weeks after it kicked in we’re wonderful no aniexity no depression I’m talking to people more before I was so shy but now for example if I see someone and they have a shirt on I like or something I’ll strike up a conversation and ask then where they got it before I’d just walk past well that’s how good I felt for about two weeks then out of nowhere I got irritable starting fights with my fiancé over nothing something as simple as diapers. Telling my mom to get the fuck out of my house because I’m not in the mood like just irritated for no reason snd very opinionated. I stopped taking them and now I’m back to being shyer than ever even shy around my fiancé who I’ve been with for three years. 😭 anyone else have any experiences like me??? I just took a pill today because I realized I’m being too shy lately ):
