I want to move out so bad but don’t know how.

I currently live in a motorhome with my family and 4 untrained dogs, so you can imagine what that is like. I want to get a job and move out but I don’t even think that would be enough to get an apartment in Washington and I don’t have a car and retail won’t pay well. I’m so fucking tired and stressed living with them. I love them but I cannot stand it, it’s horrible for my mental health. I don’t have anyone I can share rent with either. I don’t know what to fucking do and I don’t even see the point in living at this point. I know that sounds dramatic, but you guys have no idea how hard it is living in this thing with my family.
