My condolences as well. And I second Arbiter's unsolicited advice, don't ignore or postpone the grieving process. Sharing good memories is a great way to pay tribute to a life that touched yours.
On edit: In fact, if you can't or don't want to get together with friends in real life, why not share some memories with your friends online. Sometimes writing is easier to do than dealing with others face-to-face. If you want to share some stories with us, we're listening.
