Shalom brother Mo2388,
I am so very sorry to hear this. My deepest condolences to you and your loved ones. As several of us have said, he is in an infinitely better place than we are.
Remember we are all one big family here [which is why I refer to my fellow JTF'ers as brothers and sisters] and we are all here for you to get through this loss. Remember, Hashem loves you and will always be with you and your stepfather.
