So sorry to hear of your loss. Putting a pet to sleep is very hard, but think of it as putting them out of pain. I've had to put 4 pets to sleep over the past 40yrs and it is not something you get over quickly. A few months ago I had to put my cat down because he had feline aids and was losing weight very quickly and the only thing I could do for him is put him at rest, he is no longer in pain, he is running around perfectly fine and loving every minute of it.
It hurts us more then them, it will take time for the pain to ease, but till then just remember your time with them and that you did what was right for them.
HOPE, FAITH AND LOVE
