What is wrong with my mom?

My mom was similar. She frequently received shots from the hospital for migrane headaches, and that made her very delusional. Is your mom on any medications? Also, there was a lot of relationship strain between my mom and dad. After they divorced, she improved, but she still has a long way to go. Finally, my mom struggled with an eating disorder many years prior, and her continual food restriction made her moody and unpredictable. Bipolar sounds like a reasonable diagnosis as well.
