I would recommend the following video that may not provide explicit answers, but will perhaps provide a contextual understanding for how you're feeling.

It sounds like you've slammed your new life full of ephemeral busywork to, well, keep yourself occupied. It also sounds like you don't have a professional network that relies on you and that you rely on (since you're financially independent and just poking around these days).
You may want to take a step back, enmesh yourself for a few weeks or months in all the possible paths you could focus yourself on (which will likely be chaotic and unenjoyable), and then just dedicate yourself to pursuing a given path. Try to build up a network, feel you are helping others in the network, and see where it all goes.
Whether this path ends up being financially fruitful or being conventionally successful along some other axis should be viewed as irrelevant given your current status. You'll likely find just having a thing to do, that other people are also working tangentially on or are interested in, will bring you all the success you need.
