Terrified to lose my dad...

I'm a single mom with a 7 month old baby. My parents are my number 1 support and have helped me so much. I am so close to them and they love my daughter and are amazing with her.

My dad has been having these awful migraines for a few months and losing his vision and they just told us the news from his latest CT scan... he had a large tumor in his brain.

I feel like my whole world is falling apart. I don't know what to do. We have so many questions and no answers as this was only found TODAY. He meets with a brain surgeon in 2 days... I'm terrified. He is only 56 he is still young... I'm so scared he wont get to see my daughter take her first steps... grow up.. she wont have any memories of him.

My daughter is oblivious obviosuly she is a baby, so smiley and happy and crawling all over the place and I just don't know how to take care of her right now. It feels wrong to smile and laugh with her but obviously I have to as I dont want to upset her. I just don't know what to do. I dont know how to get through this.
