For a while, I wasn't even able to work properly. And I started having thoughts like, "maybe I will never recover and be able to support my family." It was scary.

I physically didn't have the necessary energy. I was exhausted all the time. I could code for an hour max, and then I just couldn't anymore. But this improved a lot over a couple of years.

But today: my physical body hasn't fully recovered from the sleepless nights, wrong sitting positions, etc. Lower back, neck, for example. I know these can be improved through exercise, and I do it more and more.
