OMG my roomate has some sort of mental illness and she did not mention it before I move in. Some days she is nice but then she can stop talking to me for days, or being super rude or slamming my door because she asked me for my charger and I said I was using it. On a daily basis it is very difficult to deal with. I get anxious before getting back home because I don't know if she is going to have a good day or a bad day. I try o be understanding and supportive but I never know what to say, specially because she change her mind about everything at least once a day so I live in a total uncertainty. For example she has been telling me that she will move out next week since last November, because she wants to live in another neighbourhood. 5 months later she is still here.
