@Androosh, i am so very sorry for your loss. i haven't lost my parents, but i've lost grandparents, and so many friends. there is no good advice, and i am sitting here feeling for you man. take care of yourself and your family.
the one buddhist mantra that always reminds me of the impermanence of life is this: "all that is mine, beloved and pleasing, will become otherwise."
thinking of you and yours.
