I feel DONE with everyone. Can anyone else relate?

I just feel DONE with all the people in my life. Can anyone relate to that? I am tired of feeling unimportant. Tired of friends never calling me unless the weather is bad or they don't have other plans. I just want to stop talking to everyone. They aren't really in my life lately anyway. How do I do this without creating conflict? Eventually some people will say "geez where have you been" and I'd rather not respond with "hey you finally noticed? **** off!". Does anyone else here ever feel DONE with everyone in their lives? Is there a psychological reason for feeling this way? Thanks.
