In short, your brain chemistry is currently in an unusual situation and that also affects how you feel about your life. My advice would be to work on feeling better. There's plenty of things that I'm bad at, not only compared to the top 0.1% of the internet, but also compared to my real life friends. But I can enjoy doing them just the same, despite my obvious lack of skill. You can be both useless and a good person at the same time. Plus chances are, others will actually value your contribution, even if it seems like nothing to you. So the first step should be to find something you enjoy doing, or to relearn to enjoy something you did in the past.
