Maybe i'm just weird like that.
No, I tend to be the same way. (To a certain degree, anyway.) If I have to grieve, I feel better doing it in private, away from the eyes of others. I prefer if the other people around me simply let me have my own time to internally process everything and they try to treat me relatively normally otherwise. Too much in the way of sympathy and platitudes, however well-intentioned they may be, usually only serve to make me feel worse.
It's hard to make suggestions as to what should be done in a situation like this because everyone handles grief differently. It might be appropriate to offer one person a hug, while another person might not want you to say anything. You have to gauge it on a person-by-person basis -- if they seem like someone who might appreciate a few words of comfort, then offer them. If they're more the stoic type, then simply just being there and talking about anything to help shift their thoughts in a different direction (i.e. chitchat about everyday things, sports, music, etc.) may be just the thing.
It's ok to feel numb after something like that happening -- it's a lot to take in when one of your peers dies, especially at such a young age. (It kind of puts life in perspective a little bit, which can be hard to process. I somehow always feel it's much harder to lose younger people than it is to lose older people. It's not that younger ones are any more special than the older people we care about, but it's almost like an extra sting of sadness because the younger person had their whole life ahead of them still.)
Best of luck, Jett.
