yes when i'm in a mania i can get easily frustrated. i have big anger issues. my daughter is also 7 and has seen me throw "temper tantrums" that i feel awful about. i don't know why my mania comes with anger. but i know how you feel. just reassure your daughter that at those times mommy is sick but that you still love her and would never hurt her. see if that might make her feel better just to tell her some of what is happening so that she might understand better.
