<human>: Give me the gist of the text in a nutshell

I'm 19 and currently still living with my grandmother, who smokes CONSTANTLY.  As in, rare to see her without a cigarette.  My aunt is also frequently here (she kinda does-but-doesn't live here, idk she's fucking crazy) and she's probably /worse/ about it.  I stay in my room all day I'm home, only leaving for moments at a time to use the bathroom or put a TV dinner in the microwave (my grandmother has horrible hygiene so I don't eat her cooking any more, and staying in the kitchen to cook my own food means I'm going to get smoke in my face.)  I didn't realize how bad /I/ smelled, though, until I recently spent the night at my smoke-free boyfriend's, then picked up my clothes the next day and realized they smelled like a pack of cigarettes.  I have my ceiling fan running constantly and sometimes I try to just wear a lot of deodorant and perfume, but that ultimately doesn't help much.

So, reddit, I ask of you.. how do I get rid of this horrible odor?
<bot>: I live with two chain-smokers and despite staying in my room, away from them, I smell like a chain-smoker myself; how to fix?
