Ignore the people making a big deal about paragraphs it's not the end of the world.
As for your issue, you really need to stop this, it's not fair on the people who become attached to "you" and it's just so deceitful, you don't need to pretend to be someone you're not! Just accept and love yourself, learn that all these boys you're talking to don't like you for you because you're actually deceiving them.
Honestly I'd advise you to take time off any social media you've catfished on, and like maybe post a public status on each app admitting you're a catfish to come clean to everyone at once. After that just try your hardest to stop, it sounds like you have some deep set self-esteem issues, if you think this is an addiction maybe see a therapist?
