Three's a crowd, two's company, but one's a riot.
There is this social stigma about being alone. The image of someone walking through life independent can be an intimidating sight. Some people might see this as selfish or sad since these are feelings we try to avoid or crucify. Being alone is both a choice and not a choice. Your body is your body, it is inevitable that your physical self is always alone.
This perception is unique only to your experience. This is an irony everyone shares but does not completely know of the other. I cannot speak to your being alone and neither can you mine. The through line here is that there are more advantages than there are disadvantages.
