FIRST POST IN HERE

First time posting in postpartum depression. Could really use some advise but not even sure where to begin. I'm currently 6 months pregnant with my second. My first is 15 months. I've been feeling really down, depressed, sometimes i wish I can sleep to the end of my pregnancy. I was just put on pregnancy disability due to really bad back pain and siatica pain. I know pain can make you depressed like, but it doesn't just stop there. I feel like my mirage is lacking, idk if it's just the adjustment of having babies and them taking up all your time but I just don't feel like my husband is in love with me. Maybe I shouldn't dwell so much on it because I'm really hormonal. Idk. Ladies!!! I'm so lost and confused.
