Sometimes I find being alone a pleasant experience. I find that the sense of self is grounded, and I can feel myself being one tiny spec a part of the universe. I can work out thoughts in my head, I can test the feeling of absolute independence, I can be my own self without being anyone else's. I am me in the whole sense of my body and my mind and the way I look at the world.
Sometimes I find being alone an absolutely hideous experience. The feeling of being a tiny spec in the universe becomes overbearing, squashing me. I've actually considered whether I've become invisible before when I've been in a town for several hours and not said a word to anyone. I start being overly friendly to shop owners and cafe baristas as my only form of human contact. Working out the thoughts in your head is all very well until you realise you keep going round in circles unless you discuss them with somebody. Hearing yourself say thoughts out loud, and having someone respond to them is just a nice reminder that you definitely exist.
This is all very dramatic, I know, but recently I've been a bit afraid of being alone. As if all my friends are the little weights on the end of helium balloons, and when I leave them for a while I begin to float up into the sky with my own thoughts going higher and higher, further away from the grounding comfort of a smile or a hug or a laugh.
