Please help

Can someone tell me what’s wrong with my eye?? It’s just my eyelid. It itches a tiny bit but other than that it’s just swollen. Definitely not pink eye or a sty. I tried a cold compress once today but seems like it’s swelling up more. Another thing Is I just started taking Zoloft 3 days ago, so maybe that might have something to do with it? There’s not bumps or anything. Hurt more towards the middle and top of my eyelid
