I don't know squat about Instagram, but your idea about starting over with a clean slate is probably a good one. As far as putting a face on your product, I would tend to agree. You are quite handsome, and you may as well let that benefit you to whatever extent that it may. Videos instead of just pics would show that you are well spoken and not just another pretty face. I was on Facebook from 2020 till earlier this year. I got rid of it because I got tired of my "friends" concentrating on politics, I haven't missed it yet!
The people following me insta are complete strangers and a few from home and I dont give a toot what they think of me especially on a path like yours you should be proud to put yourself out there. Do not worry about what others think of you. Those people have moved on and so have you. Life ain’t all about posting your stuff online
