My stomach hurts

I’m living in a closet. When i try to stretch, my feet bump into the wall.
When i try to stand, my head hits the wall above, and my mom and i barely fit in the closet. With no windows and not even a door.
My mother is getting sick because of all the dust the closet starts making.
I and her are getting sicker because the guy who rents us the closet has a family of 7 people. They are noisy ALL day and all that noise goes into our closet. Its so noisy that we can’t even hear ourselves think or hear our own TV. The bathroom was suppose to be for only the roommates which is me my mom and this other new guy that just moved in next to us in a closet that actually looks like a room and has a door. But EVERYONE goes to that bathroom and leaves it looking worst then a public bathroom! Then they make my poor sick mother clean their crap.
We have reached our limit. WE WANT TO MOVE. We hesitated because before we moved there, we were in the street. It was raining and we would have to ask people for a dollar just to save enough for a hotel room. This effected me a bit as well as my mom. Its just me and her. Alone. We don’t have money anymore and my mom’s job is so slow. She cleans houses but they aren’t calling her much. And now that i turned 18 i am looking for a job to be able to help her out. But right now we are trying to find a place we can afford. The guy was renting us the closet for $250 and now raised it to $380. We can only afford something around $350. Its so hard. I don’t know what do do. I feel like crying and running out of that house. The kids of that guy are always saying horrible insults to my mom and i. The guy laughing at us. And then stealing our stuff and taking out more money out of us. I wish i was living in a peaceful place where i could call home and feel free. Where instead of insults i would get smiles or at least a simple nice hello. I can’t take it anymore. i wish someone would help us.
