I told him to leave....

My baby is 10wks and my other son is 15months. I have ppd and my husband is unsupportive. I've talked to him about it and his answer is, there's no such thing. I can't handle it anymore. It has gotten bad to the point I don't leave my house. I've gone to cutting and I'm just ready to end it all. I told my husband yesterday to leave and I want nothing with him. I'm tired of being like this. I want my life back. I know I'm stronger then this. I'm making myself an appointment tomorrow and hopefully I get put on something cuz my babies deserve better. My husband or should I say ex husband will no longer control my life. Please ladies tell me this will get better?? I was always one to say I'll fight for my marriage but there's nothing good from keeping him around. I don't need to hear there's nothing wrong. Cuz I know there's something wrong in my head.
