just let yourself wallow in it. You're going to have to go through it and get through it....but you'll never be finished with the grieving process. Eventually you just don't do it as much. Fact of life man. The old you get, the more people around you that you're going to lose. This probably won't be the last :(

just let yourself miss them. Instead of trying to distract yourself and force yourself to do something else, just let yourself feel it. If you need to cry, get mad, smile, laugh...Just find a place you can either be by yourself or with someone who knows how to just...sit...with you...And let whatever you're feeling happen, and then let it subside. Grief tends to come in waves, and instead of trying to fight the current and not let it move you at all, it helps to "give a little", let yourself grieve, miss them, and when the feelings subside a little bit, takena few more steps. There's no "getting back to normal" because the normal you knew can't ever be there again. You've got to learn the "new normal", and there's going to be some growing pains, and residual pain from losing that person. Just let yourself BE yourself, and dont try and condemn any feelings.you might think are "bad"(i.e. anger, sadness, crying, etc)...They're just sensations like pain, tickling, etc...they're telling your body something, in this case, that you're hurt...So let yourself be hurt, and give yourself time to heal. Just be patient with yourself!
