But who cares about psychology, this is writing. This is stories. And-
Story is conflict.
Something must be at odds with something else. Whether it's your protagonist against outside forces (like another person/s or the elements) or your protagonist pitted against his inner self. Stories with both kinds of conflict? The best!
If everything is all fine and dandy- well, who wants to read about that? Readers will complain that nothing is happening in the book. Not saying that there can't be "perfect" moments in your story. A good writer will set up that scene where everything is bliss, and then take the protagonist spiraling down back to earth where we all have troubles.
Yes, bad things happen to everyone. It's a realistic thing. So if you want to have a realistic story, then bad things must happen to your characters. Sorry to you characters out there.
If your character's supposed to be heroic, a hero can't go without a few troubles triumph, or else he doesn't seem very heroic, right? If he's supposed to be virtuous, his virtue must be tested.
Now it is a strange thing, but things that are good to have and days that are good to spend are soon told about, and not much listened to; while things that are uncomfortable, palpitating, and even gruesome, may make a good tale, and take a deal of telling anyway.

So it's okay. Maybe we are a little weird. By other people's standards. But it's a necessary part of writing. So feel bad, yes. To stay human. But story trumps all. So tell Carlleta Lynn O'Casey that her troubles are all for the greater good of the story.
