Your post about Linus was absolutely amazing; what a bond the two of you shared! You were so lucky to have him in your life. IMO, you will grieve for him and miss him for the rest of your life. It will get easier, and you will learn to live with it, but the loss of Linus is something that will always affect you. And considering the bond you obviously had with him, I would be surprised if you weren't still grieving for him. It's obvious that you and he adored each other.
