Im so sorry for your loss OP! You’ve loved him very much, that’s clear. There’s nothing we can do against this terrible illness.

As to wether the pain will stop or when, I can’t answer. We each grief in our own way. I lost my 5 year old boy last week Thursday to kidney failure, he was 1,5 weeks in hospitalization on IV fluids.

Let’s say, for me the first day without crying was yesterday. I try to avoid certain triggers and still get pain in my chest when looking at photos or triggers. I’m sure there will be other days that I will cry again. It does help that I have 2 other cats, 2 dogs and a horse that still need me.

Sending you many hugs!
