Indeed, sounds like a bad day at work. And true, we all have them once in a while. I would suggest that it really depends on how many "bad days" there are, though, whether or not it's really a bad day, or a bad job, or a bad fit. Only you can answer that.

As for noisy neighbors ... I personally enjoy silence a lot. I would love to live miles from anyone. Can't afford it though. Sometimes my neighbors are quiet, sometimes they are noisy. And OTOH, sometimes my kids and dogs are quiet, sometimes not so much. And different people have different levels of noise tolerance. What is "screeching" or "screaming" to you or I might be "laughing" and "playing" to your neighbors. There really isn't a "right" or a "wrong".

Legally, most towns have noise ordinances, which kick in after a certain time, generally about 10:00 pm. So, if people are indeed screaming loudly after that time, you probably could call the police. But at 6:00 pm or 8:00 pm ... highly doubtful. They cannot legally cut across your grass. But is that really the battle you want to pick to start the war?

As Karen said a polite conversation - when you are not angry or frustrated - might work. Worth a shot. But if the parents think their kids are simply playing and laughing like kids normally do, there really isn't much you can do at 8:00 pm. It is outdoors after all.
