It sounds like you hate the law. in which case you should drop out. On the other hand, I will say that from everything I've seen and heard the practice of law is different from law school in some very important ways. For example if what you hate about law school is that you spend all your time soaking in knowledge and not enough time actually producing work, that will obviously change somewhat should you become a lawyer. Also if what you need is more feedback for what you're doing than measely grade at the end of the semester that can be different as a lawyer too, depending on the job. It might be worth it to figure out what it is you hate about law school. If it's grappling with decades old decisions and weird quirky doctrine, then yeah, that ain't changing.
If you've already paid your tuition for this semester it might be worthwhile to finish it out while you look for your next step. If that's the case I highly recommend joining some student practice organizations or volunteering somewhere during the semester. I think I would like law school a lot less if I hadn't had the experiences of going out into the community and trying to do some good. Every time I don't want to crack my Contracts book or fiddle around on Lexis trying to get a search that will give me some good caselaw, I think about the skills I am gaining, and the credential I will get at the end of this process, and what it will allow me to do. On Friday I was in an organization's office with a sectionmate and we were fielding calls and sending out information packets and I turned to him and said "Having fun?"
"Yeah," he said. "It feels good to be busy." I think implicit in that statement was "It feels good to be busy doing something positive and useful." You might find that too.
I think the vast majority of 1Ls go through moments of doubt and wanting to leave. Reports of depression are enormous. But most 1Ls also, in my experience, find things they like about law school and reasons to go on. It might be worthwhile to look a little harder to see if there are reasons you might like it too. If there aren't, then at least you will know that dropping out was the only choice that could make you happy.
