I want to post of TikTok but I’m too scared

So I’ve always wanted to post content on tiktok and stream, but I’m so scared to do so. I post pictures of instagram, but for some reason, the idea of me posting content on tiktok or streaming makes me so anxious and scared. The thing that scares me the most is my friends and partner finding my content. Since I was really young, I hated people in my life finding out my interests because I was always shamed for them. So I’m a pretty private person with what I like. But this fear is preventing me from doing something I’ve always wanted to do. Can someone give me advice please?
