Help me escape a horrid landlord

Hi everyone! So I'm not usually one to go out and ask for help like this. Most of the time if I need money I will just buckle down and work as much as I can to get by and pay the bills. But with Christmas coming up and multiple vet, medical, and rent costs piling up I have resorted to asking you lovely people for help.

I have been going back and forth from doctor to doctor about the possibility of having some form of cancer. I'm waiting for the most recent testing results back to confirm or deny their theories. I work part time at a supermarket so that doesn't really pay the bills easily, but I am trying tirelessly to find a better paying job with more hours.

I also recently happened to find a kitten, which I named Starlord, abandoned not too far from my duplex and just couldn't let the poor guy starve and die. Now after multiple sessions of shots, flea medication and getting him neutered those bills are starting ti pile up as well.

The main reason I'm trying to raise money is so that I can move out of the duplex I am renting from my grandmother. The rent she is charging me is managable but the problem is the utility bills that she claims I owe. I live by myself with another person on the other side of the duplex we rent from her so you would think the utilities would be next to nothing for me. Somehow though my grandmother claims that I have racked up over $400 in one month. I'm rarely home due to working and try my best to use little to no electricity, gas, or water so getting the news that somehow I've worked up that much for utilities seemed a little dodgy to me.

My grandmother in the past has managed to figure out numerous ways to wrongfully obtain money from people. One instance she opened up multiple credit cards in my aunt's, her daughter's, name and proceeded to take thousands from my aunt due to debt and late payment fees. So I believe that my grandmother is just trying to profit from me renting her duplex instead of putting my money towards the bills.

I'm working to save up enough money to move out in January or February so I can finally be free from my grandmother's constant harassment and manipulation ways. If you could give anything at all to help me I would be so very gracious Thank you so much for your time and help guys!
