There are a lot of small to mid-size tech companies that actually make money, though maybe not unholy mountains of it, where work-life balance is great and people just want to make something customers love. There are also many agencies that fit that bill.
This risks sounding too simplistic, but in life I've found that work tends to fall into three categories:
1. People who want to get as rich as they possibly can. 2. People who want to make a living and enjoy life. 3. People who want work to be their passion.
I've learned to avoid #1 and #3.
Re: #1, Many of the best ways to get as rich as possible involve screwing other people over. The people who play that game and enjoy it end up being pretty cutthroat, because that's kind of the point. If that's not you (and it's not me), then it's not fun to be part of.
Re: #3, vocational "passion" is just hard. Sometimes this is because the dream is so big -- end world hunger, or something. Sometimes the dream is so popular -- become a world-famous artist, etc. This is where you'll find the dreamers and the starving artists. The people who thrive here sort of live in their own world where the more mundane concerns of life don't matter to them, otherwise they'd burn out and give up.
A lot of people think they need their work to be either about Riches or Passion (or worst of all, both), and so they go down those paths and find stress, exhaustion, and misery instead of happiness.
Meanwhile, in boring old Path #2, you have a whole lot of people who work from 9-5 and then go home. They think their job is kind of interesting, but they don't think they're "changing the world," and that's okay. The happiest folks here tend to be craftspersons who know how to make some kind of thing, and whatever it is, they make nice ones.
As for me, I spent years that I look back on now as a sad waste of time hunting for #1 and #3, before one day having basically no choice but to take a "kinda okay" job so I could buy groceries. I was badly burned out, and I decided I needed a break, that I'd take six months and just "work a stupid job" to recover and pay off my credit cards after my experiment in running my own business fizzled out. And after six months I realized I was the happiest I'd ever been.
Life is kind of weird. It's not glamorous or sexy to just work a regular job and go home at 5pm. But it can be the foundation of a really happy, satisfying life.
I don't know if that will help you or not, but, I hope some part of that is useful to you. Many people have been where you are now. It'll get better.
Good luck!
