How am I supposed to not get depressed if I work at a factory..?

I hated my manufacturing job so much. It made me depressed and I lost interest in all my hobbies at the time. Factory work is hard on the body and mind, gives you no breaks and makes you tired when you finally get home. I quit but I cant find anything else. Everytime I ask for advice I get told I should just suck it up and deal with my job but most of those people never worked in manufacturing and have no idea how bad it gets I dont know what to do.
