I hate my job.

I hate it. Ive been here 2 years and constanly get told by my manger how stupid i am. Almost everyday i work 12 hours with no break. I have to csrry things pver 100lbs and when i drop something because i have a bad back i get called stupid or lazy. I do my job then have to help do someone elses job. I make minimum wage because i cant go back to nursing because of my back. (I fractured it and it healed wrong.) today not even 5 minutes and they told me yo go home and because a new person wanted to close tonighy but i had to take their shift so now friday i work 5am to 3pm then 6pm till7am. I really hate this place but im afraid no where else will hire me because i can usually only work 3pm to 12am since i run a business out of home during the day and have a family to take care of.
