But what is required?

One of the hardest things is missing something you don't have. For example I miss my family, but I can talk to them and I know that they are right there when I need them, all the time. Here right now I miss a close friend, I haven't got one yet. And to be missing that person is not easy at all because you can't call him/her, I don't know that he/she is out there when I need him/her. Actually I don't think he/she is, because I really need him/her now. And you think you're doing your best, that's why it's so hard. For sometimes it's not enough that we do our best, sometimes we have to do what's required.
