Markus, this was a no-win situation. Yes, you felt some guilt walking away at the vet's office, but had you not done the right thing then, and instead watched your pet deteriorate and suffer, you would have felt guilt about that too, and wished you had done something sooner.

I get that. I think those of us who have lost pets ALL get that. But what about experiencing the the feelings of joy and laughter and love and happiness during the years you had her? What about experiencing THAT again?

I agree wholeheartedly with MrsD and those who encourage you to allow another pet to receive your love and share your life.

God, grant me the serenity to accept the things I cannot change,
Courage to change the things I can,
And wisdom to know the difference.

You cannot change the loss of Minki, or replace her, but I don't think that's the way to look at it.
You CAN change, without guilt, the fate of another pet, and fill the hole in your life left by Minki's loss.

There is no hurry, but there are many, many pets waiting for someone like you to love them and give them a home. One of them needs you as much as you need them. It would be therapeutic for both of you.
