why am I being shown this message if I don't even post anything? (read desc)

I've never posted anything on my tiktok account that I've had for literally years. the past few days I started only reposting some videos and now I'm getting this message? what should I do? I'm scared about losing my account.

I can't post pictures so here's what the message says:

"We found that your account is posing as another person or organisation in a confusing way. as a result, your account will not be recommended to others. you can edit your profile or submit an appeal, if you believe this was a mistake."

but when I press edit profile it just shows the same message again and I can't do anything, I'm scared if I choose "submit an appeal" I'll lose my account or something.
