I've been feeling exhausted lately and very empty. I don't know what to do with myself or how to cope when I'm feeling this way. I also feel like I don't know myself at all and don't know what to do when I'm not around other people, I feel like this is contributing to my sense of emptiness. How do I get to know myself? I feel like I get waves of inspiration but they never last and i just end up feeling empty again. It makes me very lethargic and like I don't have a purpose.
