Made up my mind abt divorce

I've decided I am going to go ahead and get w divorce. I can't take this anymore. This constant feeling like I am alone even tho I am married. My husband (soon to be ex husband) got an attitude bc I woke up in a bad mood Due to postpartum depression & didn't tell him that was what was wrong w me but he knew that I had previously been going through it & just bc I don't cry every day I do most of the time. Plus what depressed person trust wants to tlk abt it!? Bc when I talked to him before I started crying & he was saying "it's too early to be crying. I just got off work. I don't wanna hear that." He was tryna say it in a joking tone but I could tell he was annoyed by me crying n tlkin abt how I felt that one week. Then he started saying he didn't care that I was going to the hospital to get help so I'm going alone. I can just be w a man who wants to help me take care of me n my son if he's going to just continue worrying abt his friends & not me n my son.
