Can you maybe start a part-time job with tiny little tasks or do a contract project assistant to feel the water? (ie. a job that ends after the project is done) so you're not too much committed and not for long time. Also try flexible work from home like Freelancer.com or similar websites (you can join for free). Most of these guys they assign you with Writing tasks (if you're a native English speaker this will pay you very well). You get to chose the topic and how much work you want to do within each task, so you're more in control.

There's no perfect job that fits everyone. But to me you seem like a person who'd enjoy a lot of freedom or flexibility.
