I Have Anxiety Attacks

I can not stand or deal with anxiety. I have anxiety too but not as bad as my mother. Her anxiety is so bad that it drives me nuts. It is difficult for me to talk with my mother when she is having an anxiety attack because she'll give me odd looks as if to say that I do not understand how she is feeling. There are several reasons why her anxiety is being activated like this. Medical, family, someone in the family keeps reminding her of her abusive past when and they give her messages from rude family members in her family (the kids from her sister who got killed over 50 years ago).

I can not deal with when someone reminds mom's abusive childhood past because she can get triggered easily by problems of today. She went through a divorce from my dad 10 years ago and he died last year.

I am sad because she seems to be upset with me and probably thinks that I do not understand her.
