I don't know yours and Spitzer's story but I feel quite confident in saying I'm sure you did perfectly by him. Your care & concern shows in all your posts, and he was lucky to have you as his mommy.
I have moments of really second-guessing myself with Gem's care, so many things I wish I'd done differently, but I try not to wallow too much I can only deal with what is in front of me now.
I honestly have no idea what to make of Gem's numbers today. Nothing makes any sense to me at all.
