Why did my mom react so harshly when I shared my depression?

I told my mom that I decided to step down from my full time job to part time. I shared with her that I feel like I wasted 3 years of my life and that God should just kill me. She kicked me out of her room and said I should go to hell. She said I just want to stress her out and that she has cholesterol.
