Where do I get the strength?

I’m not happy with my boyfriend of 5yrs.

I don’t love him anymore but I moved 300 miles away from home and I can’t afford to live by myself. How or where can I find The strength to leave?

I don’t want to go home to my family, I like my new area and job. I just won’t manage by myself and I’ve never been alone before. It’s still a new area with trying to make new friends.
