I don't know what do about this

Why do I lie to get sympathy and attention? I feel like a terrible person but I don’t know how to stop and I don't know why I would be doing this. What is wrong with me? I would meet someone and lie about things not actually happening, invent fictitious people and over exaggerate events.

People eventually figure stuff out and end up hating me eventually. I don't want to keep hurting people
