People are social animals. Wanting to be seen as interesting by others isn’t in itself a bad thing. It’s a matter of degree.
You describe it as an “addiction”. That suggests to me that you think your happiness depends solely on what others think; that you aren’t able to do things to please only yourself as well. The question, then, is how to bring things back into balance.
Genuine self esteem requires not only feeling good about yourself but doing worthwhile things that show you deserve those good feelings. In your case, it means doing worthwhile things that only you know about. Identify some need in your community that you can fill consistently and privately. Get involved. Do what you can. Then let yourself feel good about it. Really take it in that you are a decent person doing a good thing.
Then ask yourself if it is enough to appreciate yourself. If not, why not? I suspect the answer to that question will get to the root of your issue. Once you know what causes your “addiction”, you may be able to get “sober”. If not, then I suggest you consider some individual therapy to help you live a life that is less dependent on others’ approval.
I wish you well.
