Giving up

I cry on my way to work now, my job is hell... I've been applying elsewhere and no luck anywhere, yet I smile like everything is ok and it isn't. I'm about ready to give up, I can't do this anymore. I stay with family, but I've been trying to get another job to get my own place because no one helps pay for anything. I do most of the cooking, grocery shopping and cleaning. Noting I do is ever appreciated. They always ask for more money out if me, but never are willing to help me with anything. I don't have any kids. I guess I'm single, idk. My significant other probably could care less, about my situation, he's trying to take care of me, but I'm not buying it... I've been trying my damnest to cover my behind mking sure I'm ok, he doesn't support me fully, I don't even feel like I'm capable of being with him, I don't feel like I'm enough. We don't live together, we live about 5hrs away. God I feel miserable, I don't feel like me. Trying to figure out what I'm doing wrong?
