Resumes...cover letters...and applications are ruining my life

So I'm filling out this application for the Commonwealth of Massachusetts for this really cool job monitoring tern colonies off of Cape Cod on the Elizabeth Islands....and after being rejected from 4 other internships in the past 7 days I've just really lost my job hunting mojo (wouldn't be the first time..haha).  The thing I don't seem to understand is why these jobs are asking for people with Bachelor's degrees and little experience and once I apply they tell me there were applicants with "extensive field experience" and wish me good luck on my hunt.  OK Ms. Fish & Wildlife Service Employee, please direct me to the job where I can gain this extensive field experience.  Please and thank you. ;)

So I've begun to realize that my time spent at Northeastern which has given me a shitload of loans was basically a waste.  I tried taking advantage of their co-ops but I guess I didn't push myself to find one when no one was hiring and because I was scared of ending up with no co-op and having no classes to take.  Then there's the whole what did I spend my last 4 summers doing issue....oh yeh...I went to Greek Camp because I really wanted to give back to my community which actually helped me get through my teenage years in one piece.  I guess in the process of choosing the best path to follow, I royally fucked myself over...at multiple junctions.

What am I to do now?  I'm a college graduate with little to no experience and it's actually all my fault.  I know I'm sounding extremely pessimistic but I'm almost 23 years old and the only examples I have in my family are two parents who had me at 24 and are now having their own mid-life crises because they had dreams and weren't able to do what they loved.

I feel trapped in my house....and overall just bored to death because I have no plan, no schedule, and no order.  I'm really scared that if I don't find like 50 more internships to apply to by the end of march then my chances of landing a job by summer are slim, and I'll have actually spent a whole year doing nothing but working at a pizza store.  I guess I could really use some advice.  Or maybe a godsend?

Sigh. :(
