As an only child, I had to do a lot of things on my own. My parents had full-time jobs, I didn't really have any neighbourhood friends and I had no siblings, built-in peers that could accompany me to scary places like after school activities and camp. I learned to cope with this, though it was never easy, especially as a kid, but I accepted it as a fact of life. There would be things I would have to go through alone, and that would have to be okay.
Now that I'm older, I've learned to accept having to do things alone and have come to sometimes even relish it. I live alone, and for the moment, can't imagine living with another person. I go out to eat alone, I go the movies alone, and this week, I went to several comedy shows alone. Yes, sometimes it sucks being out and about, surrounded by happy couples or laughing friends, but there's also a freeing element about being out alone. I can leave when I want. I can do what I want. I don't have to worry about someone else having a good time. I can make sure I have a good time, and I do.
I know it seems scary, but it's so empowering. It's okay to be alone. It's okay to want to be alone. No one is judging you, no matter how much you think they are. And if they are, let them. Play by your own rules and enjoy your time out. You deserve it.
