Problem

I have a rather uncomfortable situation at home where I see that my mother blames me for everything . Today's situation killed me, the fact that the mouse appeared in the house was according to her 100% my fault. She said hat because of me she has depression that she has a mental breakdown that she will have to take antydepresants that she is fed up that she has a shitty life. I don't know what to do I just want to get somewhere but I'm in asshole. I have a dog and for less than a month no one will rent me anything. I have saved money but not enough to buy an apartment, in addition, from October 1 I'm going to study and go for 1 month to the dormitory. I don't know what to do and I really ask for help ....
