I'm staying with my friend, and her daughter is an 18 year old autistic, low-functioning girl who is intellectually disabled. She literally never stops talking and screaming from the time she wakes up until she passes out. She also is always running as hard as she can into my door. She's playing with her imaginary friends, who honestly I wish would just die. I tell her to be quiet, but she just ignores me. If anyone tries any harder, she'll just have a tantrum and start cussing you out. I'm ordering some noise cancelling headphones for Black Friday, so I just have to get through a few more days. I love her, and before I moved in with them I had no problem with her, but this has been going on for two months and I'm about to completely lose my mind.
