Mum In Pain

I woke up this evening and father told me mum is in great pain. It has been for 1 day since yesterday but she didn't tell me. My brother knew about it. Somemore when I was asleep she went to wash clothes. Why don't tell wake me up and tell me to wash or wait till I wake up. I am angry with myself for being insensitive and being so sleeply. I should have realise she is in pain and should not go and rest then I won't sleep. I always wanted to help with all housework but some times when I was resting or sleeping or out for a while she went to do. I know she feels bad when she can't do any work but I want to help her. Because today I was asleep my brother think I never help with house work but the fact is I did. He never seen me doing during weekday and think I never help.
