Look up "Borderline Personality Disorder" and see if it sounds like your mother. If not that, there may be other disorders that better describe her.
There is clearly something wrong with her. It will probably help if you get a better understanding of it.

If she has always been this way, look up Borderline Personality Disorder and similar problems.
