The "Why you shouldn't go to law school" articles are absolutely rampant. I can provide you with 30 more if this is something you are actually considering. For many people it's a terrible idea, and everyone should make that decision with their eyes open and aware of the potential downside. 2011 graduates have a 60% employment rate right now, at least in jobs that require a JD. Yet, almost 100% of graduates leave with some kind of debt, most in the 6-figure range. If you don't graduate from a top 10 school (think Harvard, Yale, Columbia) then you had better graduate in the top half of your class if you want to obtain a job that can pay off your debt load. (Tuition inflation is partly responsible for the high cost of legal fees btw)
So, yes, going to law school is a bad idea for at least half of everyone who attends. Far too many people attend for the wrong reason, and not everyone can excel. It's kind of sad, but a risk that one takes. Fortunately I am in the top 10% of my class, and as long as I stay there I will have my choice of six-figure offers in any state I should choose to reside.
Speaking of poorly made educational decisions, what can you do with half a Geology degree? Overall, do you think it is a good or bad idea to attend college if you can't manage to finish? Was the debt worth it, or were you at a cheap school (community college, third tier toilet, etc)? You can't apply to law school until you have an undergraduate degree, so if this is a route you are serious about you will need to apply yourself in the short term and finish that up, then you can focus on the LSAT. If you need any advice, let me know. I excelled both in obtaining my undergraduate degree and taking the LSAT. I'm happy to give you some pointers.
