I'm so sorry you have to go through this. Odin is a gorgeous boy and it hurts to let him go, of course. Give him all the love you can, while he's with you.

I agree with what Freedom said:

At some point, you say, "this is not right, this is not fair, this is not how I / we want to remember him."
Sending Odin lots of kisses, and hugs to you.

Take care!
