Yes, this feeling is relatively constant in my life. There are times where it is more noticeable though. Usually getting lost in the moment is the best way, but that is hard to do on purpose
I don't know if I can relate. When it really bothers me, I try to do something about it, go out, have fun. Surround myself with people whose company I enjoy.
Sometimes the feeling persists. Its usually when I try the above and fail though. When its not satisfying, when the people I'm with are just kinda whatever. -shrugs-
