Oh my god! I know how you feel. My mother has a friend who suffers from bi-polar disorder so she falls out with her family a lot. She is actually really scary when she hasn't taken her medication and I tell my mother I feel uncomfortable when she is in our house but my mother just doesn't listen. Sometimes the woman could stay in our house for up to two weeks in a row! Luckily she hasn't visited in a few weeks but I think she is gonna visit in the next few days.
