Who told you you were wrong? That's ridiculous. For what? Liking video games? Making people laugh? Enjoying socializing on the internet?
Like sure, being on the internet all the time isn't a good thing (I wish I were on it less tbh). It seems as though the person in question here is either finding that what you're doing is "unacceptable"...whatever that means...or is just a negative person.
Idk, you do you. You gotta be yourself, I've learned. If you spend too much time trying to be someone you're not, it takes a lot of joy out of life. I may have changed some things about myself since I was in high school, but my core values and interests haven't entirely changed.
Stick to your values, who you are, and don't let other people try to tell you otherwise. Unless, of course, they're genuinely concerned and are having a meaningful, not toxic conversation with you. Then maybe consider changing a tad.
But otherwise? You do you.
