I'm severely depressed and my anxiety is driving me off the wall

I've tried Zoloft before pregnancy and it made me feel like a zombie and physically and mentally slow. I was wondering what else to do for depression and it also gives me anxiety to take meds.I cry at least once a day and I don't want my baby to have those sad hormones either. I tend to get overwhelmed at night especially.I've tried to do coloring Mandela coloring pages and it's surprisingly helped a little bit but not much because everything just tosses through my mind.
