This is a video that I found and thought would be helpful. There is some really good advice in here. This video is from 2010, but the information is very relevant. As a reminder, if you are having trouble making any payments for your student loan, you should contact your loan servicer immediately. Often, they can work out something to help you out, whether that be a new payment plan or a deferment or forbearance.
As a reminder, the worst thing you can do is nothing. You should always check your mail and answer the phone when they call. When you are delinquent, the servicers will not go away. When they stop contacting you is when you have to worry the most, because you have more than likely defaulted, and things get much worse at that point.
