I think people have a strange perspective of people who are alone.
You might eat alone and people probably assume that you don't have any friends. If you enjoy doing things alone, people might make you feel bad. You might even think that there's something wrong with you because you prefer to be alone most of the time.
I feel you and I'm here to confirm that there's nothing wrong with you.
Needing space is totally normal. It's safe when you're by yourself and no one expects anything of you. It's really important to be able to enjoy your own company because it makes you more independent.
In life, no ones going to hold our hand do things for us. We're going to have to be adults and do things like big boys and girls.
I love doing things by myself. I prefer reading over socializing, I like going on walks by myself, going to the beach, and going to the movies. There's nothing wrong with that. The next time someone makes me feel weird for doing things alone I'm going to ask that individual couple of questions:
Why does the idea of being alone scare you? Is it because you're insecure with yourself and can't stand to be in the same room as yourself? Are you afraid of being lonely? Do you realize that if you never learn to love your own company, no one will truly appreciate your own company?
Being alone can be liberating if you let it be. A sense of independence washes over you and no longer rely on anyone in order to do what you want to do and I wish more people appreciated isolation.
Being alone isn't automatically associated with feeling lonely, don't fear it, embrace it.
