I know that your heart is broken. It is so, so hard to lose our babies and I don't really know what to say to comfort you. I hope that Simba passed peacefully. I know that he knew he was loved. And you know, whether our babies are blessed with long healthy lives or have lives that are cut tragically short, like your beautiful Simba's, the one true thing that we can know and pass on to them is our unwavering love. And don't ever think, no matter how young or old they are, how aware or how sick, that they fail to know how much we love them. Our unending love is one gift we can give our babies that they will ALWAYS need and want. And I know you had that love for Simba--and be assured that he knew how much he was loved. And your love was the greatest comfort he could have, then or now. May your beautiful, sweet Simba rest in peace. I firmly believe that you and he will be together again one day, in a wonderful place. Until then, Simba will be happily waiting for you.
You have my very deepest sympathies for your tragic loss. God bless you, and God bless sweet Simba.
