Most people who complain about being alone or lonely are this way because they choose to be

They’ve had others show interest in them, but they always find an excuse to push them away. Because they know they’d have to actually work on themselves in order to have a connection or relationship with another person, and they’re afraid of what they might find out about their real self if they actually tried to do that. So they find it easier to accept the devil they already know, and find some excuse (too busy, too hurt by past trauma, too old, whatever) to push them away, and continue telling themselves that they will be forever alone and lonely because they are no good for anyone or don’t have time or whatever the excuse is.

We set the goals we wish to achieve for ourselves, even if they are not good for us. Even if they make us damage ourselves, or other people. It’s up to us to wake up and realize who is really at fault, and change it.
