Input: Quick background: I live alone in a one bedroom apartment. My younger sister has been homeless the past 2 weeks and has been begging me to let her stay with me until she finds a shelter. She is a meth addict, drinks excessively, and schizophrenic brought on by heavy drug use. Half the time she makes no sense. She was also recently released from jail for stealing a car. The jail doctor also told me that she has **lice and scabies.** 

I try to tell her to join drug programs but I can only do so much. AITA for not letting her stay with me, and letting her sleep out in the streets in this cold weather? 

Thanks for any responses.
