I am sorry to read that your life is so difficult at the moment, but you have done the right thing by having the courage to reach out for help.
I know you say you are looking for ways to cope with your situation, but I totally agree with the previous post. The fact that you're looking for strategies to cope, shows how normal this behaviour has become in your life. It's not normal, the level of domestic abuse you are experiencing in absolutely unacceptable.
Maybe you could try contacting an organization such as www.refuge.org.uk
or speak to your local citizens advice bureau, who could put you in contact with local agencies who offer support.
There is a room here for family, friends and carers, which may offer a different perspective on your current situation, but I can't imagine you would be advised to stay in it.
I hope things get better for you soon and please keep posting.
