Would you marry or stay married to someone who isn't compassionate about mental health...?

I've had anxiety all my life and anytime I've ever had an anxiety attack he gets mad and screams at me telling me I need to control myself.. I'm developing depression and again..he screamed at me and told me I need to go get medicine and stay at my mom's for a while.

I'm due to marry this man in 2 months.. he's pretty good guy other than no regard for my feelings. We've been together for 4 years. I don't really know how to "just leave" even if that may be best..
