Ride a bike. You get exercise, sunlight, cheap transportation, thrills/adventure, and good feelings, it's a win win

And if possible, find a local social bicycling group near you. Adds even more benefits when you are riding with a group

A cat? It forces you to do something useful everyday, which will make you feel good. Maybe a dog is even better, since you'd have to walk it, but a dog is a harsher commitment than a cat. You can't skip a walk with a dog, just because you re having a bad day. A cat however, will be fine for a day of neglect as long as you keep it's bowl full. A cat also enjoys playing outside though, so you could try that as well.

I had a kid, which didn't cure my depression, but it took away all my time. I didn't have time to think about depression anymore, so I kinda forgot about it. Though I wouldn't recommend having a kid for anything besides just wanting to have a kid.

For me, it was running and reducing alcohol to very moderate levels. I'm at the point now that I crave a run to clear my mind and lower my stress. I rarely ever feel depressed anymore. Total game changer for me.

Whittling is also a good one, low investment and relatively simple.

Drawing of course 😁! I think it would help to get your emotions out.

Hiking, biking, walking, and jogging are all solid options.

Firstly know you are not alone, lots of people feel like this. I suggest a hobby which includes exercise and meeting people. Exercise releases endorphins and generally energises you. Meeting people helps bring you out of yourself and focus on something else. I do gym classes as it means I am around people but don’t have to interact too much. It’s the same people so I say hi and maybe chit chat a little. A gym buddy is good if you can find one, we never liked to bail on each other so used to go quite regularly. Swimming always makes me happy and my cat! (She likes to paddle but not really what I meant!)

Learn programming?

I'm positively surprised that I've not seen gym suggestion within 10 comments.

Juggle. You must have 3 similar ball shaped items around the house. There's lots of tutorials online. You get your blood feeling, body moving. Such a nice rush when you finally get that new pattern or trick you were working on.

Turn the passive watching into something a bit active if you can. I like watching TV, and I sometimes try to analyze the data from them. Similarly, if you like watching youtube videos, maybe examine what it is that excites you about them, if any, analyze and introspect.

I’ve thrown myself into competitive powerlifting and my bipolar disorder has been stable for like three years. The exercise can be tough but it really levels me out.

Wow, you're being bombarded with good suggestions. Although I'd like to add an ingredient that helped me with my constant boredom; if you are going to go exploring or hiking, I found going outside to be incredibly dull personally unless I kept my mind occupied.

For me, that was creative writing brainstorming (plot, character development, etc) almost like organized daydreaming. I'd write it all down when I got home. Although I never did make the game given time constants, I had fun thinking of worlds of my own design.
