She is driving me crazy!!!

Remeber I have a roomie who is a circus geek.Days ago she told she was moving out,I felt so relieved hearing the Great News.But,she didn't tell me when .Recently she was even was,she keeps fighting at me on and on.Nomally I don't see her much,but I have to face her when I want to cook,we use the some kitchen,then her rage just begins.Blame me over old issue I didn't even remember.I cook as fast as I can to get away.Guess what,she stopped me from leaving the kitchen,force me to get it straight with her.What?Those chores I totally did't remember,like I shouted at his boyfriend when I was waiting for him to spare the bathroom?My God! I don't even want talk about it.She just can let me go,she is driving nuts.When I managed to escape from the kitchen,I don't have any appetite anymore.
God help!How can I deal with that.Now I hope my boyfriend can get back soon,he will give some comfort.
