Man, that really sucks, but as everybody else said, better to just let go of that the sooner you can. Of course it's a thousand times easier to say it than to do it. That is one of the main reasons I still don't have a pet... because I love animals, and I know that if I had a pet I would love it like if it was my little brother or soemthing... actually my step dad had a little doggy like 2 years ago, and I came to visit, and i really loved that stupid dog... well, now the dog got lost before I came here again, and just to think about him makes me feel sad. And yes, no offense but your friends are stupid idiots. (regarding that, at least) And always remember what Fortune said, that precious gift you gave them, which I'm sure was returned by them as well. Animals DO give love if it's given to them.
Hey Fortune, I'm sorry to hear that about you
That kind of periods in life are very hard to go through, but unfortuantely they are unavoidable and it's in one's own decision the key to make them "softer" I don't think I need to tell you this anyhow. Just to let you know that I got concerned.
