Do you ever hit that point where you're bummed and don't want to talk to anyone? You're better off doing your own thing and interacting with no one. I hit it all the time. What do I do when I get this way and friends still need me? I don't want to abandon them or pretend I don't care, but I simply don't have the emotional energy to support them during those times. It's hard enough to maintain my own sanity.
Some days you just need a break.
