Do you have anyone you can talk to - a friend, relative or someone in the court system? I'm sure you should be able to find someone who could help. Being in the UK I don't know how the system would work for you so can't give any specific advice. We do sometimes get people on here posting from the US, but they obviously haven't found your question. It must be frightening for you to see your mother losing control - try to stay calm yourself and not get drawn in, it will help her also.
