It's a sad day

When my grandfather passed away my mom called me and woke me up to tell me.
This morning my mom called and woke me up, and told me that we were going to be putting molly down today. I'm torn apart. It's too soon, she is only 4, and I've been gone for the past year.
I'm incredibly sad, and very angry at the same time.

I'm going to miss her.
