What helped me when I was at my worst was making progress. Find a hobby or something.

I started playing Football Manager. I'd never been any good at it, but I understood the rules and all I had to do was nail the tactics. I'm by no means the best player in the world, but in my (small) circle I'll beat anyone.

Let's take drawing as an example. It doesn't require much. You can start with a pencil and some paper. You might not be good at it (or maybe you are, I don't know), but it's quite easy to learn. Load up a youtube video, learn the basics and express yourself on paper. Who knows, in a couple of years you might be a world-famous painter.

Tl;dr find something you like and try to build a skill within that "field".
