Every day I wake up dreading work

Hi everyone I recently turned 21 and got a job in a warehouse about two months ago, the moneys good but 12 hour days are so draining and the way the work is set up they track everything second you do I can’t stand it

It sucks and I really been having this episode of wanting to quit every day, I don’t have a job lined up exactly but I can go clean windows with a buddy of mine and try starting our business

I’m blessed enough to live with my mom and have very little expenses so I don’t need the amount of money I’m being paid now but I’m honestly one of those people that feel pathetic quitting and I can’t make myself do it

I could really use some advice or anything from people who have been through it or are just older with more experience
