It's a tough question. If you hadn't started yet I think I'd tell you to give some consideration to doing something else. Unless you are going to a state school or someone else is paying your way, the three year cost of law school is enormous. If you finance it (which most people do now), the payment becomes a huge burden on your income after you graduate, especially as a young lawyer when you aren't going to make much. The general public has a misunderstanding as to what the average lawyer makes. While there are certainly some lawyers who do very well, most new lawyers outside of major metropolitan areas are only going to make about $50k. While that's not poverty level, if you throw in a monthly loan payment of a grand or so, you're not going to get rich either. There are a lot of other jobs you could do, that don't require that level of education, where you could net the same amount.
I usually tell people who ask about law school, don't just go to go. If it's something you always wanted to do, that's great, pursue it. But if your not sure what to do with your life, and you think law school might be "interesting" or might buy you some time, think about some other less expensive and time consuming options. The other thing to consider is that in addition to the cost of going to school, you are going to give up three years of your life/career/income that you would otherwise be devoting to something else--and which you would be that much farther along in by the time you graduate.
But given that you've already started I think I'd stick it out for a while, especially since you've probably already paid tuition for the semester. I also think having some initial concerns about being at a new school, and the general stress of first year law school is natural. Don't give up on it for that reason alone. I'd give it some more time (and agree that finding some legal work outside of school will give you a more realistic look at what it's like to be a lawyer.) But if you still have serious reservations a few months down the road then think more seriously about what else might be better for you.
Good luck.
