Hi Amy- you will be able to live, but the amount of loans you have combined with your other bills will be dependent on the lifestyle you live. Make sure to do as much research as possible on loans as well as scholarships so you can be sure you're only borrowing as much money as you need to.
Post-college, I dialed back my life-style. I had roommates, cooked 6 days a week, and used public transportation. The additional savings went towards making additional student loan payments. Make sure to leave yourself enough room to still have fun! Your 20's are a great time and you should have enough to go out with friends or go on a trip!
