Have you ever lost a friend?

I mean like not dying (well it can be but that's not what I mean) but maybe from like moving away or just growing apart. My friend moved last year across the country and it's really saddening me because we were such close friends and now I feel like we don't have that special friendship anymore. I know she has new friends and I'm happy for her, but I wish I could still be with her. :( I still talk to her, but it's not the same. So have you ever lost a friend, how?
