Kat-

Slow down and try to organize things for us.

1. What was this event? No need for excruciating detail.
2. What is the cause of your sister's antipathy towards you?
3. Was your sister involved in this event?
   
4. What are the reasons that your children have taken a stance against you?

Other than trying to have a discussion with the parties involved, you will not get much that is very helpful until we have more data with which to help you.
