When i was young, my mother opened two credit cards in my name and used them to start building my credit history. So by the time i graduated college I already had a 750 credit score. She had always paid them off on time but i never really had access to the cards or the log in to monitor the accounts.

Just this year she lost her job and without telling me built up a lot of debt on them and defaulted on both of them. I caught it right when they hit my credit report so they are still 0-30 day late payments period. I right away cancelled her cards, left the accounts open to save my oldest accounts, then payed them off but the damage is already done and my credit dropped 150 points just from that.

Is there anything else i can do to get those late payments of my account or do i need to just wait for them to drop off? I believe since i payed them entirely off right away it shouldn't take too long to go back to normal but I am in a very competitive housing market and this might make it really hard for me to even rent a apartment.
Just a note 

A) I realize i should have watched those accounts, i was young and completely forgot i had them.

B) The maxes on the cards were very low, so it wasn't a huge hit to have to pay them off, i'm just really worried about my credit history.

Also If theres nothing to do to save my credit history now, how long can i expect my credit history to be hurt from this?

My mother built up a lot of debt on my credit card accounts and now I have to pay them off. How long do I have to wait for the negative impact

Stop suggesting to press charges. I understand thats one way to getting something removed from credit history, but unlike most of reddit, lawyering up isnt the solution for everything.
