The vet told me my cat only has a few weeks left to live.
Thats so terrible! :( Im really sorry... you should do something special everyday and make memories! 
I plan on it! He is really old so it is just his time to go and I get that but that doesnt make it any easier.
It really doesnt.. i had to put my dog to sleep and it was extremely painful. I really hope that he can rest without pain and that you can feel better soon.. 
Yeah It is just one of those things we all have to go through at some point.
