So tired of my life at the moment

By time I was 18, I had been living alone and overseas from my family for two years. I had a full time job with management responsibility (in a call centre, graveyard shift) on top of full time studies, a serious relationship and was covering all of my own costs including fees.

And I was a complete slob Even though the places I lived were "mine" in that I paid all the expenses, I was perfectly happy living with all my clothes on the floor, having just one set of sheets and eating plain pasta for dinner every night. I think a switch must turn on at some point which turns you into a moderately functional person.

In the meantime, though this is clearly stressing you out. She needs to respect you the same way she does other people. Lay down the law, I say, or she can move out and see if flatmates are willing to put up with her habits.
