I have to get this this out.... and I'm sorry if I am winging and sound like a total B***H

I live with my boyfriend in a tiny, and I mean tiny one bedroom unit... I have to describe it, it's essential to the story, hehe!!
ok, as I said.. TINY!!! one bedroom, bathroom/laundry together, tiny lounge and kitchen... really designed for one person, but usually it suits us fine. It i s actually a beautiful, modern unit...

Anyway... my b/f has allowed his brother to live with us for the past month and a half after he and his g/f broke up and he had some troubles...

I have never been so stressed in my life... I suffer GAD anyway.. and was only diagnosed recently after going through a traumatic event... So, I took this semester off university to relax and sort myself out.... I go back in 2 weeks, and so far, have not had a day to myself to relax... I dont know what to do!!!

It just makes me sooooo angry, and I can see myself being a total b***h all the time to everyone... and I am usually a happy, bubbly person.

I have tried many many many times to talk to my b/f about this, and he is just as stressed as me, and doesn't know what to do... but I still am sooo angry at him for being sooo ignorent.

Along with this, there are many other problems going on, such as money - trying to support his brother as well, as he is jobless.... and also me having to sit here for 8 hours a day with him while my b/f goes to work....

I am almost at the point of saying "it's him or me" .. and if I go, I am not coming back.....

What am I going to do??? I know there are all the options like go stay with family etc but I dont want to leave my own home...
