Having a "boss" is something that happens as a result of anything needing hierarchical organization, regardless of pay, though. I'm not sure if you've done much volunteer work, but there's pretty much always a string of people in charge and you'll still largely be taking orders to ensure that you and everyone else are actually contributing in a helpful way instead of just dicking around.
If you don't want a "job" you probably just want a hobby.
If you hate having a "boss", you can always become your own by starting a company.
In software, you can get into consulting and contract based work. That way you can be somewhat selective about your clients. Focusing on finding contracts where the work you do is contributing to something you value personally.
Having multiple clients also empowers you to feel like you can so "No" to a client without worrying that you will lose your only source of income.
Also, hobbies are a great way to offset the stresses that come from working on projects you do not enjoy. Spend your free time working on something you enjoy, simply for your own joy.
Also, word to the wise: It's important to remember that no matter your employment status, you are _always_ your own boss. It is your life you are living. Choose how you want to live it
Or try a hobby that doesn’t require work at all, but rather play, with friends. Simple stuff - throw a disk around at the park, play some cards against humanity, etc.
