So sorry about Blossom. She looks just like my Inkling! I've had the same experience of not really connecting to or feeling close to an animal for quite a while, then finally getting that closeness for all too short a time. It left me feeling that I didn't love them quite enough, even though some of them didn't seem to be that interested in me even though I tried. I now make an extra effort with those. It took 5 years for Panther to let me pet him, and I'd had him since he was 6 weeks old.
Just remember there will never be a kitten shortage, so take your time adopting. You'll know when you're ready. I wasn't planning to get another cat, but fate brought me 2 kittens yesterday. We found them in the middle of the road.
"Some of you say, "Joy is greater than sorrow" and others say, "Nay, sorrow is the greater." But I say unto you, they are inseparable. Together they come, and when one sits alone with you at your board, remember that the other is asleep upon your bed." Khalil Gibran
