What to do for this?

I’m 31 weeks pregnant with my second. My first is 13 almost 14 months. Since I hit 3rd trimester I’ve had bad depression and anxiety. Same thing happened with my son and then it got worse postpartum with him. Is there anything I can do to cut down these extreme anxiety thoughts and worrying and depressed times...? Anything to calm me at all? I feel like I’m going crazy every single day. I also have had spd since 20 weeks with her and now have sciatica where I can barely walk I’m in pain all the time. Can anyone give suggestions..😞?
