I went through a really similar thing. I went to college, and absolutely hated it. Hated high school too. And college was SO expensive...so I dropped out, was taking part time classes just for the fuck of it...and eventually stopped doing that and worked.
I just needed time to really figure out what I wanted to do. Just out of high school and into college I think is rushing things too much. I needed to go and work for a while and figure out who I was, and what my role is in this world.
And I really, really hated working full time for shit money too. A couple years of that whipped me into shape and got me serious pretty fast.
So with all of this in mind, I finally found a school that really fits my learning style (Evergreen) It's largely independent and self-study work....and I am so into what I am doing (Ethnobotany and Ecological Anthro), and so full of passion about it. But I couldn't have figured that out where I was in my previous school or in high school. It takes support from your parents and your educational institution to make those decisions. And if your school isn't giving you what you need, look elsewhere.

My overall point is it could just be the school too. And if you need time to reflect on yourself and what you want to do, then do it. But don't burn your bridges though. And I've also known people that get a BA in x and go to grad school or get a job in y. What you major in does not dictate your life path. And Anthropology is one of those fields like psych that is very flexible and applicable to many different areas of life. It definitely opens doors....and doesn't close any.

I work as a physician recruiter and love my job. I have a degree in Anthro from Berkeley which really doesn't have much to do with my line of work. But having my degree is what made me stand out to them in the first place. It's worth having just for that. You'll always have an edge in the marketplace, so to speak. Do it and be done. Then you can move on. It really doesn't take all that long considering the benefits it will bring you in life. And be sure to have fun with it! Anthropology really is a fascinating and varied subject. :)

for most jobs just getting a ba is what matters. it doesn't matter what it's in! if you hate college just do the major that you find least painful and plow your way through it. college isn't for everyone but it really will let you make a lot more money.

^^I don't believe this at all.^^

Job experience will get you a better job than college. I had a BA in spanish and anthropology, they got me nowhere professionally, but socially they were great.
