Law school is hell, that much is true. Whether or not you make friends, deal with backbiting and underhanded BS, and all that depends on the school you go to. Some schools foster an environment of excessive competitiveness, while others, like the one I went to, try to recruit people who will, at the very least, be civil. I made quite a few very good friends, and while we disagree on politics, we still make a point of visiting each other and grabbing dinner or drinks whenever they come into town for business or vacation. You succeed in a profession by being respectful, courteous, and honest. Law is no exception. In some town, New York being one, there are so many lawyers you can get away with being a jerk or a cheater, but in most areas and middle-sized cities, the legal community is so tight-knit that people who act that way get pointed out and labelled. I have colleagues whose every word is put under a microscope by judges because they're either sloppy or unreliable. I have others who are taken at face value - what they say in court is taken as fact because they research thoroughly and say nothing to the court that isn't true. TV is entertainment. Actual practice is nothing like that. And if you have grand visions of being a trial attorney, know that 95% of your work will be done in Microsoft Word. Your motions, your briefs, and your memoranda will do almost all of your heavy lifting. The trials are just a song and dance for the benefit of a jury after the real battles are fought.
For work load, expect to study at least 60 hours a week, and even more when papers come due or when finals are around the corner. You read between 100 and 200 pages of material a night, and are expected to know it well enough to quickly recite the facts, issues, rules applied, holding, and result. without flipping through your books too much or wasting time hunting for things. You will need to learn criminal law, contracts, torts, civil procedure, criminal procedure, property, constitutional law, secured transactions, bankruptcy, commercial paper, wills and trusts, family law, and probably a couple others I've forgotten. You'll probably be able to learn oil and gas, individual tax, partnership tax, corporate tax, gift and estate tax, banking, environmental law, administrative law, labor law, specialized issues for death penalty, children, education, specific constitutional amendments, health care, federal securities regulation, mergers and acquisitions, consumer law, as well as a handful of practical classes that dovetail into legal aid clinics, moot court, and the like. Oh, and before I forget, you only have one final exam that determines your entire grade for the semester.
You will be cold-called. You will be questioned, backed into logical corners, and likely humiliated at least once. You will have at least one nervous breakdown and will at least once question whether you made the right decision. If you can't find a job, which is the case for around 40% of law school grads right now, you'll probably consider suicide as the only way to escape your $120,000 in student loans (none of which can be discharged through bankruptcy) and the humiliation of wasting three years of your life on a degree no one seems to want just to go back to living with your parents. You will wonder several times, "why didn't I just get a masters," while chugging whiskey straight from the bottle.
And then, once that's over, the real fun starts. You study for the bar, hopefully pass, and then spend the rest of your life living the dream, working 60-80 hours a week earning barely enough to pay your bills and keep the jackals you owe money to at bay.
