Hey Tree,
you did so well and I am so sorry for your loss, I know its very painful. You did the humane thing for your cat, you let him go peacefully without struggling on in pain and I think he would be greatful for that act of what is ultimately kindness in the end!

I am really glad you called your T for the moral support because it's am emotional time for you - completely understandably!

I am so glad he's giving you extra time on Thursday, he sounds like a lovely T who understands your needs and the importance of having support.
