Can't sleep.

I was wondering if everything I thought was my life was a lie, a illusion. Do I even know where I'm going? What I'm doing? I just know I don't want people to feel alone. I hated being alone. I still do... But maybe I should everyone needs to learn how to alone. But i just guess i'm just scared of that if I'm left alone again will it stay that way? I know that it's unreasonable but I still feel that way.
