Upset with husband

Please tell me if I’m just over reacting.... so a week ago today I finally sat down and admitted to my husband that I have PPD. I even admitted that I’ve had suicidal thoughts.....I cried and told him everything I’ve been feeling. He said he would be supportive and try to help me....fast forward a week later and he’s become very distant, has hardly touched me and seems angrier and irritated with me now. I told him I need help and he stayed later at work every night this week, I’ve asked him for months to call off on a Friday to stay home and help me. Really thought this Friday he would have done it and when I flat out ask him this morning if he was going to stay home today he said work was more important, even though he has plenty of PTO time. I have a hard time doing anything for myself, so last week he talked me into scheduling a pedicure for myself and then today he tells me that he has some things planned at the same time I scheduled my pedicure, so I ended up having to cancel it. The one thing he did do was talk to my doctor today and ask about what needs to be done for PPD ( He works at a hospital) when he saw him walking around. He called me and told me to message him and he would get me in contact with who I need to speak too. I did message him today, and after waiting all day I never got a message back. This is why I never ask for help. It doesn’t matter if I ask for help, or if I sit here “acting” as if everything is fine, because it doesn’t make a difference. I don’t know why I thought it would be different this time. It’s just easier to go through life acting life everything is fine, even though it isn’t!
