Talk to Psychiatry on Psychiatric Problem

AOA! My mother is 47 years old. I think there is a psychiatric problem with her. She has been married to my father since 23 years. The problem: She has too strange mood swings. She is always fighting over nothing. She shows symptoms of pressured speech. (When annoyed, talks aggressively, doesn't care about her surroundings, Says what comes in her mouth, says nonsense, she doesn't even know what is she talking about) She has some kind of ego problem also. She can't let herself down. She lies bluntly just to prove herself right. The major things which provoke her to act like above are interaction with either my dad's side of family or even her side of family. She can't see them. since 23 years whenever she meets with them, she always become angry. She can't control herself in angriness. She thinks for hours creating fake scenarios about these family member and when she fight she don't even know what is she talking about. she spend hours of sitting alone and thinking nonsense.
