Grief

I don't want anyone feeling sorry for me or anything like that. I just need some advice about how to deal a bit better with the loss of a friend. Whenever i go somewhere or see something that is really nice or any little thing it always goes through my head " oh yeah i will tell my friend about this" and then i have to keep telling myself that i can't because he's dead. It happens everyday. All the time. Like i have to keep reminding myself that i will never be able to talk to him ever again. I find so many things i want to tell him about but he is gone. I miss him a lot. I know it is supposed to get better with time but this constant forgetting that hes dead and then reminding myself is really hard. I go for a drive in town and keep seeing his car thinking o there he is i will wave. He was not a boyfriend or anything like that but he was a good friend for about 15 years and he taught me so many things and i could ask him anything. I feel a bit lost.
