Parents opened 2 Credit Cards in my name

Hey Everyone, long story short, I noticed that my credit score dropped significantly from 750 to 628 since December. I knew that something was not right and did a credit report that showed 2 new credit cards opened in December under my name without my knowledge. Both cards are maxed out at around 3k total plus interest. I saw that my address on the credit report was updated in January to my parents current address, one that I have never lived at or used, which gave me the suspicion these accounts were opened by my parents. When confronted they admitted to it. I am 21 and graduate college in my few months and was counting my credit score to help me finance a car this summer. I called both banks to report the accounts as fraud, filed an identity theft report with FTC and submitted a fraud alert through Equifax that is supposed to also alert the 2 other credit bureaus. I’m not sure what else I need or can do to help with this situation, any advice would be appreciated.
