I need some advice..

I had my second son 6 days ago and it’s been nothing but wonderful. I’m also suffering from postpartum depression as I did with my first born. My mother came down to help me for 3 days after I had him, then she went back home so she can work. I keep crying non stop & worrying. I really just miss my mother and need someone to talk too. We never had that mother daughter relationship but lately it’s been going good. I haven’t told her how I felt but she does know I’m suffering from depression. What should I do ?
