It’s going to crush me

My moms dog is getting old. She’s literally 18 years old and I’m 23 so she’s been around nearly my entire life. She has congestive heart failure and is on medicine for it. On top of that, she’s gone mostly blind to cataracts. The only reason she gets around is because she has the entire house mapped out and knows exactly where everything is but she will run into us and other things if stuff is moved and we are pretty sure she’s going deaf too. She’s started pooping and peeing in the floor again because she’s gone senile. We all know that quality of life is deteriorating and it probably will be soon where we have to make the choice to have her put to sleep.

Nearly 2 decades with a family dog man... it’s going to be equivalent to a human family member dying. It’s going to crush not only me but all of us. Wtf are we gonna do.
