No amount of job switching or career advice will fix that issue.
If you keep chasing the magic job that will make you feel fulfilled and content with life, you will spend your whole life searching.
Even when working for a laid back company I feel stressed with all this.
I’m sure the same stress is in other jobs. Sales people have their targets and seem to get fired more easily. Support people deal with irate people all day.
Not sure how to solve your problem but if you can live more cheaply, try to do 30h a week or less, maybe figure out what kind of programming job would be less stressful, and scratch some side project itches in your spare time with friends. I reckon that might help.
As for the depression - go see a professional right away. That’s the #1 priority. Book it now.
Anyway, if you enjoy solving problems go work for academia, they're always hiring programmers, they pay next to nothing, but you won't be stressed (unless you fuck up somebody's thesis) but otherwise it's pretty easy. I did it for 5 years and it was the best decision I ever made: working with post-docs and grad students bleeding information from them, total autonomy to do what you want, union position so impossible to get fired, you get a letter from the post-doc's shilling your abilities you can use for grad school. Look at your local universities for these positions, guaranteed no local student will take them because they don't pay enough.
Deleted code is debugged code. There is a fallacy that more lines of code means a better world. Why not try doing things that don't require coding skills, and try doing more point-and-click things. Personally I only code if I really have to and my livelihood depends on it (but luckily I can now afford not to code and focus on other things). I recently switched to doing social media marketing for a small handful of clients. It's good money for what is essentially managing a few Twitter & Facebook accounts :)
This stuff is just bits and bytes - don't take it too seriously.
Are you familiar with the State → Strategy → Story framework?
Before you can solve the work/career piece, get out of your mind and into your body.

"Programming" is a very broad category. Since you enjoyed CS and working on problems at university, there could be specifics of your current work situation that are stressing you out. You could analyse your situation and identify which aspects are stressing you out. Is it the technical issues, the management's expectations, the lack of peer support, the constraints of the environment, etc?
Once you have identify what specifically causes the stress, you can plan changes that give you more of what you like and none of what causes you stress. And, yes, there is more to life than programming.
And if you had always been handed, maybe you should go on a trip. Go visit other countrys, see other peoples problems maybe you could solve, go see how they live. The whole world needs different solutions for many problems.
You can either work normal jobs(preferable) and work part time on that goal or you focus mainly on trying to help see that change happen.
Takes things slow though and remember it does not have to be a grand goal or better you can try working on a very small part of a grand goal, for example if you are interested in climate change being solved you can help this happen by eliminating one of the bottle necks that people have to believing climate change in the first place; access to verifiable data, you can build a platform that collects this data from goverments and institutions around the world and make them available to the average Joe in visual parsable form.
It is either that you are definitely more interested in one than others or you are more suited skill-wise to another one or you are a 2nd degree connection with someone entrenched in another. One of these should come into play and be the deciding factor.
