SUBREDDIT: r/Advice
TITLE: Dog of 5 yrs passed out. Now in E.R.
POST: Of course when there is no where else to turn, I summon the internet lingerers like your self. 

First off I love my dog. He's my best friend. Sounds cliche, but its true. I paid so far $500 to start treatment. I knew this day would come, but never knew what I would actually do. I always figured because of money he would be better off being put down. But I cant do it! I dont want to live life without him. I feel as though it would save a lot of heart ache if I did just let him lie easy. Maybe I am being cheap. But even if he is better in the morning, its only a matter of time before it happens again. I take care of him and give him all the love I can, but maybe he would be better off and so would my heart if he was to be put down. I think everything will be okay, just I have no where to vent. So thanks for reading.
TL;DR: 
dog got sick out of no where. Passed out and is now in ER being treated for god knows what. Need comfort or any advice to help me through another human endeavor.
