After my mom was diagnosed with diabetes, she started to eat a lot of healthy foods and exercises regularly. This makes her blood sugar lower than she's used to and she becomes irritable. This has happened a few times. She'll come into my room at night and be really angry, but she's in this kind of trance. She doesn't really know what she's doing and she'll be mad. She's hit me a couple times and left marks on my stomach and face. Then, the next morning, she'll be all happy and won't know where my bruises came from. I know she's not a good liar so she really doesn't know what she's doing to me. I don't know how to fix this or tell her about it. (My mother doesn't have a drinking problem, a drug problem or a brain problem, she's completely normal).
