Trying to be positive.

You can always try setting up a fish tank (at least 10 gallons). Those things require enough care to be considered a hobby, especially if you want to include live vegetation. Sourdough bread baking is another option. You literally have to "feed" your sourdough starter regularly to keep it functioning and ready for bread making. And who doesn't like fresh bread? Assuming you don't have a gluten allergy of course 😅 There's always gardening as well, even if it's a tiny windowsill garden.

It might be kinda stupid but find a rock and make it ur pet! You can make it a house out of cardboards and maybe even dress the rock up!

i get REALLY easy arts and crafts projects. like paint by number or puzzles. Its auto pilot and time-consuming.

Crocheting is my hobby! Try it out it’s difficult at first but once you get the hang of it it’s repetitive and relaxing! And you get to make cool things like beanies and blankets

I grew some herbs in an indoor garden last winter. I liked being able to smell them and use them.

One of my hobbies is carving. With carving, you get to choose what you want to make and then you just work for hours trying to get the layout. It’s hard work tbh but it helps you stay busy and you can paint it after if you want. It can take hours to days to weeks sometimes (depending on what you’re making and how big it is) and you can buy the tools at your nearest crafts store and you can find a big branch anywhere too or just buy wood.
