I get this a lot. I'm kinda in one of these spots right now and it's pretty miserable. Wanting attention isn't a bad thing though so don't beat yourself up! Craving attention is just part of being a social human being. The thing is that you gotta figure out what you like to do and just damn well do it. Setting aside 15 minutes is how I start. It doesn't have to be anything complicated. Just treat yourself! The more fun you can have by yourself the more that will transfer into having fun with other people. You have to relax as hard and chliche as that sounds in your current state.
