Well, you are in a tough spot — and you’re not alone. You borrowed a lot of money to pay for college, presumably to get a better job. Now your salary won’t allow you to live and also pay your loans. You’ve tried all the places and techniques I would ordinarily recommend. A Sallie Mae loan is not a federal loan, so it does not qualify for “forbearance”. It does qualify for a deferment if you’re still in school. Or you can make “graduated” payments based on your income. Have you contacted them to review all your options? Read this section of their website for all the possibilities.
The only way to really get out from under this burden is to get TWO jobs — work day and night — because the longer you wait, the bigger the burden will be as interest adds up.
