I Feel Worried About Paying Off My Student Loans

So I found out my loan payments are interest only payments. The payments are only half the interest. If I keep going like this they'll never be paid off. So now I have to pay double what I'm already paying. 300/ month soon to be 600/month. I dont have enough money for this. Haven't found a stable job yet. College wasn't worth it. 60,000 total in loans.
