Sertraline and Pregnant

I am 35 going to be 36 weeks on Sunday. I have been very very very depressed since after my 1 yr old was born to being pregnant again. But this pregnancy has been 100000% worse. So my aunt told me she sees it in my face and the way I go about my days. And so she called the doctor and told them I need help before it's too late. The Doctor Prescribed me Sertraline 50mg. I took my first one yesterday and I got the nausea side effect pretty bad. About 5 mins after I took it out of no where I got a huge Panic/Anxiety Attack and was freaking out and then took like a 3 hour nap. - ANYWAYS😌 I've read online that this med is a Category C medicien which can cause autism and deformed/ disabilities. I know I'm at that mark but I'm going crazy thinking "did I just put my baby at risk????" I mean I want to take the med to see if I can be a little happy. But I can't hurt my baby. I already have a 1 year old that yells and screams and still wakes up at night. And not just wake up but EVERYTIME he wakes up he is yelling/screaming on the top of his lungs before he even OPENS his eyes. Mind you he does it ALL DAY LONG 😔 to where I've been thinking about just letting go. I love him, both my babies. But I'm lost and don't know what to do anymore.… it's sad but it's true and I feel bad saying or even thinking about it. But I need a break. I've been a homeless stay at home mom for a year. I don't think I can do this much longer without help.... Sorry for the Rant/feelings talk.
