Sigh.
disco_barred, trying to describe it a while back, wrote:
When you're 20 grand+ and 14+ stressful weeks deep into your first semester of law school having received zero meaningful feedback while staring down the barrel of 3-5 exams where you'll be competing in a zero-sum game with everyone you've just met in order to determine which of you have a chance at your dream job and which of you are going to be struggling to obtain any legal work at all, you'll understand

10 material facts that make 1L year (often artificially) extraordinarily stressful:
1) The stakes. Even HYS these days, but definitely all schools below, have a large chunk of their class - 10, 20, 40, 80% (it just goes up as you go down in the rankings) who will struggle to find meaningful employment. On the flip side, the top of the class are going to get ridiculous and snowballing rewards for their work.
2) The uncertainty. Every law school grades (most) classes based on a single final. You won't know going into it where you'll land.
3) The randomness. Stories abound of random law school grades. Even top performers with top top top of the class grades sometimes just randomly get a bottom of the class grade. There are reasons, but it is hard to understand, which means less control.
4) The competition. Everyone wants to do well, and people are often very overt about their studying. But you don't really know how you're doing OR what must be done to do well, so it's hard to effectively respond.
5) The uniformity. Every fucking law school in the country is teaching torts, property, con law, Ks, crim, contracts, and civ pro. On a curve. Every fucking law school in the country is full of students who want to get plum jobs. In undergrad, your stress could be alleviated by alternatives. Not everyone was in the same race. In law school, EVERYONE is doing the same thing and EVERYONE wants the same goals that some (small fraction at the best schools, huge fraction at the worst) will never get.
6) No chance to learn by doing. You MUST GET IT RIGHT THE FIRST TIME. OCI - for the big firm jobs and prestigious summer PI gigs that everyone wants - will happen after two bites at the law school exam apple. Fuck up the first time, stumble a bit, take a while to expose your brilliance? Sorry! Biglaw only hires after your first year. Tough luck!
7) The debt. Even if you're on a free ride + stipend, you don't get these years back if you fuck it up.
8: The grades fetish. How do you get the best jobs? Good grades and professorial recommendations. It's disgusting but irrefutable that the legal industry slathers over grades (and the school that awarded them). There just isn't any other way to get people to pay attention to you for the best positions. And a dirty little secret about professors - the best way to impress them is on a law school exam. Profs remember the names of the students who do well in their classes, and place phonecalls for students with glowing transcripts.
9) The law school exam. These things are designed to be obscure, time pressured, horrible means of examining and separating and sorting you. It is nothing like any exam you've ever taken, and it's a god awful blackbox from which few students - top or bottom of the class - actually emerge understanding WHY they were ranked or sorted in any particular way.
10) The curve. Your best may not be good enough, your worst may be stellar. This again speaks to the lack of control - you can't ever be right on a law school exam. Ever. It's not like O-chem where you can learn it, not like history where you can memorize it, not like your dance class where you know you're good and put in the effort. All of your effort will be relative, and you know that any strong performing peers are LITERALLY hurting your grade in order to benefit theirs.
Final note - things I didn't include (amount of work, difficulty of the material, cold calls + public speaking, etc.) are the things people expect to make LS stressful. They alone would make it not markedly different from college stress.
Also, pre-ITE at the top schools 'everybody gets a job' mentalities meant that for many people it WASN'T that stressful, because the stress factors outlined above were irrelevant if below median was good enough to pull down six figures. Well, it isn't anymore. And at lower ranked law schools it never was...
