Help where I live is too small now & I think I want to try?

I think I want to try assisted living.Where I live now the room is too small I can barely fit my full bed in it it takes up most half of the room. Then she has a desk in here and i only have my tv and my fold-able chair & my closet & the closet is full with my stuff because my previous room was bigger then this at my last place. I pay 350.00 for this small room & I only get 674.00 a month which is from SSI.I have a small 2 yr old dog aswell but she has 2 dogs I also recently have been having mice problems which I can not afford an exterminator put down traps it's no use. She b**ches when I go in the kitchen and make something because I supposedly I make too much 'noise'. And she is just a clean freak & when I have food in the fridge she will eat it or when I have alcohol she will drink it.I have SSI I have been trying to get a job & I can't. Also living here during the summer it just gets really uncomfortable because the house is SO old & when its hot it gives like 10 degrees warmer in the house.I have been thinking about getting assisted living.I am bipolar,adhd depression & aspergers. And sometimes make careless decisions due to that Help!
