OK, if the phyisical issues have started you need to get out...
I am not saying end the marriage... But you can't deal with any of this living in the same home with someone who is abusing you like that... If YOU are ILL from his ACTIONS then he's abusing you... The atmosphere isn't healthy for children either...
Get to a safe place then you can run exposure at his workplace and to family and such... Right now you need to get to a safe place... deal with the marriage once you aren't subject to abuse directly on a daily basis
