what happened to my tiktok account?

i wanted to make a new account and when i did, i think it probably deleted my original account because it didn’t make me put in an email or anything. once i created the account, it looked completely different. it told me i had a time limit and basically the whole set up looked weird. i deleted the account and then i tried to log back into my original one. it said account does not exist. what do i do?? i had so much stuff on there
