I have a sedentary job as a software developer so it’s good to be more active.
...
would you continue this hobby even though it’s wrecking my hands
As a software developer who also has fucked up hands, no. This is your meal ticket. Don't mess with it. Being depressed with a job is way better than being depressed without a job and a disability.
I've actively avoided activities that use my hands because I don't want to mess them up more. It sucks, but that's where we're at.
I don't know what activity to recommend. I do leg-centric stuff: swimming, inline skating, snowboarding, and soccer. I don't know if those would be good for you.
Edit: sorry. That came across as hostile. My hand situation is managed, but it still gets to me. I'm trying to say that you should take care of yourself and your hands. The short-term gain of an activity that messes you up isn't worth it.
Exercise feels great, and I hope you find something that works for your mind and your body.
