I know how it is to have a hobby where it's hard to find someone to share it with. Really niché stuff some of it. I find that my hobby comes from a passion for doing something for the fulfillment of doing it. Or the enjoyment of the end result.
When it feels like a draining chore I some times realize my hobby has grown into a commitment, a chore. Not something that lifts me and brings positivity any more.
I guess it's no longer a hobby but just something I used to enjoy. And often miss enjoying. But everything changes, such is life. Sometimes it's time for me to move on.
