It looks like you've met almost all of the PSLF requirements! You just need to switch to an income-driven repayment plan. If you are currently enrolled in the 10-Year Standard Plan, any payments you have made so far (while employed at a public service organization) may retroactively count towards the 120 payments needed for PSLF, but you'll need to enroll in one of the four income-driven plans in order to receive PSLF. Fortunately, these plans generally reduce your payments.
Before committing, check out the PSLF Calculator to see if pursuing PSLF is really a good move for someone with your loan balance and income. You can find it by clicking on "Calculators" at the top of this article!
If you decide PSLF is your best choice, you can enroll in an income-driven repayment plan by contacting your student loan servicer or through your Federal Student Aid account at www.studentloans.gov
