Depression risks

I’m 30 weeks pregnant and baby is weighing low. I’ve been in depression way before my pregnancy, it just got even worse after I found out.

I don’t really want to share why I am depressed, but right now my baby is important and I’ve heard anxiety or depression can cause these risks in pregnancy like low birth weight. I’m really concerned I really have no one to share this with. I want to know how can I cope up with my depression and keep my baby safe ❤️
