Lost tiktok account

I logged out of my TikTok account earlier, i know the username and password so i thought logging in would be fine but it keeps sending a verification code to an email i didn’t even know exists.
It won’t tell me the official email, just the first and last letter and the @gmail.com. I’m so upset, i have everything on that account and i can’t get back into it, what can i do? Is there any way to get it back?
