Help, my flat mates are making me want to leave uni...

So it all started off great, but then things rapidly went down hill. Within the second week of uni, a lot of my food had gone missing. Things like chicken etc. I ordered 2 pizzas, garlic bread, wedges and coke from domino's with my friend from another flat. I Had 3 slices of my pizza she had 1/2 of hers.. the next day i came back and everything was gone. They even took all the tops of my yoghurt's in the fridge and licked them and left my cheese on the floor.
I addressed all this, one flat mate told me to "get the **** over it".
I then started to hear that flat mate and another 2 flat mates bitching about me (very personal things) often when they think I couldn't hear (all boys), I addressed it calmly but still nothing changed, and I feel on edge when ever I'm around them.

With all this being done, I came home drunk and angry one night and I lashed out and accidentally knocked a glass off the side, the boy who glass it was is angry. I got so ill the day after I couldn't speak and wanted to talk to him in person and apologise, but I couldn't leave my bed for 5 days.

That weekend him and the other two turned nasty. Knowing I was ill they played loud music and ignored me when I asked them to turn it down, called me a "****" constantly knowing I could hear them, they threatened to hammer my door down in their conversation. The threw things at my door all through the night to keep me awake, they shouted "**** you" down the hallway all night. I felt so victimised by those boys I stayed in my room because I was afraid to see them the whole weekend.

I don't know what to do.. help!

Make a complaint to the flat owner.
Simple as lol , also gather evidence of all this abuse you're facing.
IF that doesn't work and the manager of the flat or what not isn't helping, move to a different place if you can.

Somewhat useful advice... if you'd said it 5 years ago
