I am scared. My roommate is laughing on its own, getting mad and shouting at no one or would create these scenarios. I just moved in like more than a month ago. Then one of our roommates moved out because that roommate had a knife to their side when the roommte just wanted to get the food delivery person up the building. Just in case the person let in is dangerous. That roommate left and I am alone with the roommate with bipolar. The roommate with bipolar entered my room twice. First, stole some things. Second, not sure. I just bought a doorknob that can be locked with a key from the outside so I can lock it when i leave. I am currently looking for a olace to live because I am so scared. I don’t even pee or get drinks anymore because I’m scared to go out.
