I Am Insecure

As of lately, an insecurity haunts me. it is that I may not have as a great personality I had hoped and that I am not weird as I had always prided myself to be.
People have always told me that I am the most interesting person they've ever met, and to never change. Told me I am unique and that I bring unique perspectives. That I am fun and charismatic and that my presence relaxes them.
But they are all from different people, experiencing different sides of me.
I'm likely overthinking this, but I can't get it out of my head.
Its that I don't make my friends laugh enough and that I am the only in the group chat that doesn't have a cool nickname.

I am tough. Why do I worry about these petty things?
Why do I seek validation through my personality and how my friends receive it?
