How to detach from your husband

I know this is not the ideal way to solve marriage problems but I come from a background where divorce is not an option. It's ride or die. After 2 years of trying to mend things...trying to convey my feelings and needs in every possible way, all I get is mental abuse, gaslighting and disrespect. I suffer from panic attacks and anxiety attacks since been married because of his mental games. I question my reality. I have gained weight because of stress eating. I sleep all day and lost my job too. I have zero will to go on.

Last night finally I was numb to his abuse and decided to make things better for myself...just me. To work on myself and focus my entire energy that I have right now on me. Now the problem is if we were living apart it would have been easier to move on. But since we live together I need help in learning how not to care and simply pretend to love him. I really need to pick myself up to get better mentally, physically and financially. Please help.
