Yes. As someone with anxiety and depression issues myself I sympathize with the sudden scariness of something like this, but it would be a shame if it just went dark because you have obviously put a lot of work into it.

If you do decide to shutter the server, set up a Github repo and mirror your code under a licence like GPL3, then maybe at least someone else can pick it up and keep sharing more cool stuff with it. It's what I did when I got out of roleplaying games.
