You could teach yourself to program. There are a lot of different sites with free classes for learning to code, and if it's something you enjoy it's also a very useful skill if you do end up on the job market again.
Everyone has such wonderful hobbies! I'd say I enjoy reading, writing, sketching (although I'm not very good at it - I still like to practice), and of course being on this site

I do digital art. Mostly Photoshop, but I also really like to design 3D models.
I learned the basics of 3D in college and I'm trying to become more advanced. Sometimes I get them 3D printed.
(I use a service because 3D printers are expensive and need constant tweaking)
