scolding

Mum is scolding everyone in the house now. I hate this. She complains too much in her life. I think she's going mad. Picked up on random things to scold about and then repeating those things she had scolded for countless times. What should i do?
Now i only know what brother must be feeling all this while. She keeps saying, " There's really no hope in this family dy". And then continue scolding. Then she'll say, " I dunno what kind of family is this! Gone dy, no more dy this family, gone!" How can she keep uttering these kind of words, it will truly bring down the family then, destroy the mental of children, me. I went away from that scolding spot. Now brother is being scolded now.
I need to forgive her no matter what. Forgive her for behaving like this. I need God's grace so much to do this.
I need to enter to university. Man, this is coming on hard on me, great burden. Mum is expecting that i enter, if i can't enter, i think she even can denounce me as her daughter. She likes face a lot. Comparing other children with her children. How can she live like this? Comparing?
Spoil the mood before camp now. Or maybe it's good i go camp later. Take a break from everything.
