Ghosting is literally one of the worst things I've experienced. I give it a 0/10 on my list of things I'd love to try again.

It makes you feel like everything said, any interest someone had in you, was all a complete sham. If you've got anxiety, it can keep your mind running around in circles thinking about what it is you did wrong and what you could have changed to make things work out. Your heart breaks a little no matter how little you really got to know them (unless you weren't that interested) because there was a potential that they'd be a great companion (at least until they completely disappeared, that is). Even if you say you don't care, some small part of you does and is just trying to put on a brave face. You wonder why all of a sudden the person is disinterested when nothing you did changed. It feels almost worse than a breakup, because you never got to experience the grand love affair that real couples do, and the ones who ghost never let you see it coming, whereas there's a small chance in a relationship.
