JUST MY OPINION - Feel free to ignore this.....

I am sorry to hear this (what you said). More accurately - I am a bit angry..... at him.

You are in pain, you are NOT getting the support you need from him that ultimately leads you to "cope" in a way that he does not like. Maybe HE should be more supportive. Sounds like his response is every bit *upside down* as your self harm is.......

Do NOT put up with his anger. You do not deserve that, you do not need that................
