I don't even know what "best" looks like, tbh. I also have some family not particularly happy (putting it nicely) with how my uncle handled it. I personally think he's a saint; views differ but there's no Right Way, I don't think. Everything is clearer in hindsight, too. It's just a severe, extended period of sadness and loss, I don't know how anyone actually dealing with it can do it for that long aside from intense love for the person. It's one of the most unrewarding things I think you can humanly go through. :/
