Hard in desperate need of prayer.

So today we got the news that my dad is going on to hospice and they don't give him more than 6 months. I am 28w4d and I am sad my son won't meet my dad or even remember him. And what makes it worse my dad won't be able to carry my son or ever get to see what he will grow up to be. How do I cope with this pain and not let it affect my pregnancy? I love my son and I know I got to do it for him but I am a daddy's girl and once he is gone I have no one. My mom is here but she prefers her other daughter and even told my husband she trust her and is closer to her than me. Please keep me in your prayer I need them bad.
