I want to start a TikTok account, but I'm afraid I'll be judged

Hi:) I'm Rina, I live in Russia, I wonder what kind of application it is and how it works. To be honest, I've always wanted to run my own blog, show parcels, shoot vlogs and other things related to blogging. But unfortunately, I live in such a mentality where it is most often criticised. What to do? Have you ever encountered such a thing?
