Have you ever felt like you lost your sense of self because of work? how did you get it back?

I've sent in my resignation for a job that has absolutely sucked my happy spirit from me. I have no time to see family or friends anymore, and I'm basically leaving this job like a battered wife. They've low balled me, demeaned me and my body is in constant pain from doubles and manual labor. I've been here almost 10 years I feel like I don't even remember who I am and need advice
