Is it normal to dislike trendy things like this?

I think this is a "duh" question I know. Its perfectly normal to dislike trends especially on this site lol. But I wanna get more specific. I have a history of having hobbies and then they become trendy and now I don't wanna do it anymore cause I feel like I'm trying to fit in when I've done it already. Considering how we live in this social media world where it kind of feels if you don't post it, it didn't happen...yeah so what if u don't post it but it did happen? Yet people will never know cause u never displayed it while others are getting credit for it cause they did post it. It also leads me to having a hard time to believe their motives. Are peoples motives real nowadays despite posting on social media? It's weird. Don't get me wrong I use social media but not as much as I want to. Part of the reason why I stop myself is cause I'm gonna post trendy, superficial things so I pause and stop myself. Although it might seem like that's a good thing, in a way, it stops me from me living cause I think so much about not wanting to be a part of a trend. I'm like "imma just do it f*ck it." And plus there's this saying "don't believe everything you think " which implies not everything u think is true on top of you are your worst enemy. I might be stopping myself from participating in these trends cause I don't wanna look bad but am I just being my number one enemy ? when its okay to participate? Is it normal to think this way? I feel like I should just suck it up and if its something I really wanna do then I'll do it regardless if its a trend. But see its not that simple, that dislikeness comes strong n makes me not really wanna do it.
