Hi Joseph. This is a rough situation, and thank you for sharing with us. It sounds like your roommate is going through a manic episode right now. Many people who struggle with bipolar disorder will do things that appear to be insane to those around them while manic. If you feel you are in danger, you did the right thing by calling the police. If you, and they, feel he is truly a danger to himself or others, they may be able to put him on a 72 hour hold. However, if you are looking for longer term solutions, you might need to wait out the mania, and have a rational conversation when he comes down from that. Work with him, and with his friends and family, to put structures in place of what to do when things like this happen. If you can't wait it out, or can't handle his swings -- part of having bipolar -- it might be best to move on from the roommate dynamic.
