Welcome to PC! I hope you find the support you are looking for and need here.
Unfortunately, we cannot diagnose your mom. I will say that it sounds like she is ill. I'm very sorry that her illness has affected you and your family in such a harsh way. I think you are trying very hard to understand and have compassion for your mom. I know it's not easy.
It might do you some good to speak with a therapist to get out all that is going on. They can help you to help yourself in your understanding and dealing with your mom. Of course, you are most welcome to continue posting here for the support you need. There are many wonderful folks here who may have gone through some of the same things you are going through.
I hope you find some peace and some answers to your questions. Please remember to take good care of yourself. Wishing you well!
