Mom has disowned me 4 being pregnant

I am 35 years old and I just found out I’m pregnant with my second and final child, I will be done after this, it’s a girl. (We already have a 6 year old boy). We are extremely excited, but my mother who has been a control freak for my whole life, still treats me like I’m 16, when she found out said she would not be there even emotionally for me because she doesn’t agree with me having another child because I am epileptic. I was just wondering if anyone had any advice it’s very saddening to me that my mom won’t want to meet her granddaughter and she’s basically trying to get me to abort the child, which I refuse obviously to do. Any thoughts, has anyone else’s mother treated them like this
