Hate my living space

I live in a small household, it’s a house that’s mobile it’s not exactly a ‘trailer’ but close. My mom and her fiancé have addiction to cigarettes, so I sometimes smell that. I’m trying to transfer colleges so I can get out of here ASAP and idc about debt this point, I feel really sad and insecure about where I live can anyone relate ?

I should be grateful because we always have food but sometimes I get shamed for it
