Welcome to the site. It is interesting how the alter who tries to put you in bad situations is the same alter who saved you after you were struck by a truck.She sounds like a helper. Do you have conversations with her? Have you asked her about herself? It is great that you stopped drinking. That change may be causing her to not be able to fall asleep. She may not be being mean by talking to you all night. Maybe she is having a difficult time falling a sleep. I am not suggesting you drink! But maybe music or leaving the tv on will help her to fall asleep. I think it might help if you ask her about herself and not to judge her. Sometime an alter just wants to be acknowledged for more than their actions. I hope things get better between you and her.
