I shouldn't have expected my life to begin the day I graduated college.
Life is a lot of hard work. The only opportunities are the ones you seek out, and the ones that emerge when dumb luck falls on your side.
Most likely, you'll be underemployed, because 1 in every 2 recent grads is. You're going to struggle with keeping your work identity from defining you as a person, and if you're unemployed, you might be struggling to get a work identity at all.
All I can say is, try, try, try. Intern during the summers, make some friends and be active in your school. It may feel all wrong to you, but figuring out who you are is an act of determination, and trial and error.
Good luck college grads! In the words of Fordham: "Go forth, and set the world on fire."
