Is it normal i'm having an identity crisis at 21?

Let me explain.

I'm 21 and have always been a good student (honors from the time they started awarding that title to graduation from high school). But when I got to college, I all of a sudden realized how many other people there are in the same place as I am all trying to do the same thing, the same way. It drives me nuts and angers me and saddens me and makes me feel hopeless all at once. My school has 15,000 students and it truly is like I am a little fish in a huge pond.

So going in freshmen year, I was too focused on engineering and ROTC to really notice all the other people and I was happy sort of. I did things and went out and felt proud to be ROTC because that set me apart from 99.9% of the rest of the population. I flunked 2 out of 4 classes (got Ds in the other 2) and was suspended until the next Fall.

I came back and did okay. It is now 2 years later, and I am getting more and more frustrated with being at school. Not only because I should be graduating in a couple months but also because I have NO idea what I want to do. To make it worse, I am just one of those students with a BULLSHIT Liberal Arts degree. On top of this is the fact that I am only taking 2 classes right now when I should be taking 4 and I have not attended either all year.

I blame this partially due to working 4 days a week back home which is a couple hours drive (the pay is worth it) but mainly because I am sick of being like every other goddamn college student just trying to get that fucking piece of shit paper that SOMEHOW entitles me to a job that I wasn't able to previously do before. I mean come the fuck on.

I believe the college system to be a system that just wants to make money and nothing else. The more kids with college degrees equals more money and this all equals a degree that is getting watered down.

So I am sick of everyone else and have become a recluse at school (something I have NEVER been before) where I leave my room to eat and go to the bathroom as well as leave to go home on the weekends. I still have 2 months to fix my class issue but I have NO motivation to do so just because I think it is bullshit that I need a degree to prove to employers I am worthy of a job.

I am considering just dropping out or probably better yet delaying my enrollment for up to a year so I can nix this semester and come back in the Fall.

My biggest worry is that should I drop out/fail out my parents would disown me and I would have nowhere to go even though I have never ever given them a tough time and have been a GOLDEN child for them. They just wouldn't understand.

What should I do and have others felt this way?
