Curses of one's mentally ill mother

I have a mother who is mentally ill. I live with her and our family. My mother gives me a lot of bad duas, she makes dua to Allah that He destroys me, that I live the life of a dog, that I suffer and suffer and end up living worse than anyone. She keeps giving me bad duas everyday. She calls me evil and insults me.

I usually dont say much to her, but sometimes my 8 year old brother hits me with toys, sometimes I will tell him off, and once I hit him back (I know I shouldnt, but he wouldnt stop and he's a big boy). She tells me I'm evil and that Allah will destroy me.

I am very concerned that I end up suffering even more in life. I know the status of a mother, but I havent done anything bad to my mother. Will Allah accept these duas? I am very worried. My dad prays good duas for me.
