THIS IS THE HARDEST DECISION I HAVE EVER MADE

I am crying while I make this list
  1. She can't get up and it is not getting any better
  2. She has known who I am since I was in 7th grade. I am 30 and I don't know if I know myself that well
  3. She is the last thing binding my now divorced parents together
  4. She is the best dog I have ever had
  5. Being the oldest child, who has always been the responsible one, is the worst
  6. I love her
