Old TikTok account

Yesterday, I lost my TikTok account because when I opened it, it said something about a password, which was weird, so I exited the app. But when I reopened it, it took mento my other account that I don’t use often. I’m trying to log back in, but it’s not working. I’m putting my username and then using my number to recover it, but it just takes me back to my other account. I was wondering if anybody knows how to log into my old account.

Thank you
