Please help me guys.

I live at home because I am 18 and it was not economical to move out at the moment, my mother wants to let a small refugee family into the house, the office we have is now a 3 person bedroom and has decent furnishings, I am fucking pissed as they smell they speak terrible English and one of them has to sleep in my room for a while and he is 15 and he is annoying, she is asking me to sleep downstairs and he has my bed. I told her to fuck off and I got a deadbolt on my door and put all my valuables on a safe

what should I do, I already have plans to move into my Grandparents House but for the time what should I do.

I am a Britfag so no guns but I have 2 Rifles and a pistol. I have quite a few people who are getting fed up with foreigners so it is not just me.
Please help me, but just know this is not common at all it is just because my mum is retarded
