What to do if I don't know what to do after college?

I graduated college a year ago in the Office Administration General and Medical program at my local college. I took the summer off before truly trying to find a job. I've gotten a few interviews, but nothing concrete so I basically sit at home being unproductive with my life. Most places want me to be either bilingual or have at least a year or two of experience under my belt.

What do I do? I'm losing confidence in my skills and I'm constantly stressed out over the fact that I can't find a full-time job. My mother and father worry for me and I hate that I'm causing them so much concern over my future.

I have been considering returning to school to further my education in the office administration field. But recently my cousin had suggested the option studying something entirely new and different as opposed to office administration.

And I'm honestly torn. I'm even more stressed than before because I don't want to waste my parent's money. I owe them enough for paying for my initial tuition. But if my job prospects don't look up I will have to go back to school.

Personally, for a job, I wouldn't mind any job as long as I am content doing it. I don't have to particularly like it, but I don't want to absolutely hate it either.

So, should I go back to school to further my education or study for an entirely different degree? I'm so lost right now.
