Hi Summer and welcome to the forum
In my opinion, and of course I am just one of the experts on this forum, it appears that you have effected a preference to your mother in repaying her loan at the expense of your other creditors. How much did you pay back to your Mum, and how much do you owe to other creditors.
As Mum is an associate of yours in the eyes of insolvency law, a subsequent Trustee in bankrupty can trace these types of transactions within two years of the bankruptcy order. So you are possibly at risk here.
I would advise you to go to an insolvency experienced solicitor for more definitive advice with regard to this issue.
