You should first contact the credit union to determine if they can consolidate your debts into one loan with one interest rate or refinance your existing debts at lower interest rates. If you financed your car through a dealership, the credit union may be able to refinance that loan at a lower interest rate. The credit union can calculate what your monthly payment will be so you can figure out if it's less than the amount you pay now.

Bankruptcy is a last resort. It will have a negative impact on your credit for several years. Also, your student loan would not be dischargeable in a bankruptcy unless you can prove that paying the student loan would be a substantial hardship.

In order to maintain good credit, make sure to pay your bills each month on time. It's to your advantage to pay your bills early, if possible, as that may result in an increase in your credit score.
