My mom wishes infertility on me

So it never fails my mom and I always get in a

disagreement and will not talk for like a month

but today she told me “I’m evil and that God will

not bless me to have a child” which made me

really upset because she knows I’m suffering

with PCOS and have been trying for almost 2

years. I am I wrong for blocking her and wishing

to have any dealings with her ever again?
