Are you religious? Turn to your higher power, if you believe in one. If not, just remember the good times your friend had. As for the older people, they were pretty bad off from what you said, and it was their time to leave their lives of pain. Rejoice in that thought. Dealing with the death of a younger person is harder, but as I said, just remember their lives and they can never really die. I'm glad you came here to talk, and if you ever want to talk anything over with me, feel free to e-mail me.
