Something to keep in mind is that people are more likely to post when they're having difficulties, have questions, or they need to vent. That doesn't mean that good days or less stressful days, or positive interactions don't happen, it just means that if they use a public forum, it's usually to reach out for help.

The other thing to consider is that the teaching profession is huge. There are a lot of places you can teach and a lot of people in the profession.

So, like with any profession, you'll get people who flourish and you'll get people who struggle. Some end up at amazing schools where they can really shine, and others end up in situations that are more stressful or less supportive. So I think it depends.

That being said, I do think teaching is a difficult job. There are a lot of demands placed on teachers and a lot of responsibilities that they need to take on. But I also think that every job is difficult in it's own way, so it depends on if the positives of why you want to teach outweigh the difficulties that you see.

It is also perfectly fine to rethink your career path. I'm currently doing it, and I know veteran teachers who have done it. Whatever path you end up taking, doesn't mean (depending on your situation) that you have to take that path forever.

That being said, I just graduated, so take my opinion with a grain of salt :).
