Yes and no. Yes it may be alright to ask your parents for help if they are financially able to help, but to be fair and honest you should only accept the money/help from them if it is a loan and you have a contract stipulating how you will pay it back. The money you think your parents have could be funds set aside for their retirement years and may be depending on that for future living expenses.
The no part is that if you ask your parents for help you are not accepting the responsibility of the credit woes you created by not using your credit cards wisely. It has been proven that those that turn to family and friends for financial help will keep on spending and using credit foolishly.
It would be best for you and your credit/financial education to work out a solution on your own. Start by creating a budget and a payment schedule to pay off your loans in a timely fashion. You may want to consult a credit counselor to help you set this up. Be sure to also pay yourself out of every paycheck you receive by depositing money into a 401k, IRA or even mutual funds.
I would also like to have you read two books that will help you with your financial education. The first one is Rich Dad, Poor Dad by Robert Kiyosaki and the second is Stay Mad for Life by Jim Cramer. Both are excellent primers for securing your financial goals and responsibilities.
