/kbin is certainly not dying, as @fr0g pointed out, work on new features and bug fixes is ongoing. However, it may give the impression that it is, and for that, I take full responsibility and owe you an explanation....
Take time for yourself, I don't think anyone's going to blame you for that. And honestly, I don't have any issues with the current state of Kbin, there's a couple bugs here and there but it's entirely usable otherwise. Finally, I think giving yourself a deadline to resolve personal issues might be counterproductive and make you more stressed than you should be. It sounds like you're already taking steps to help spread the workload around, I would just keep spending a little bit of time helping out the team do some stuff you can't do until you're able to get a better work life balance or something.
I guess I'm trying to say, things are great to me and I imagine you're getting that unfortunate side effect of only having people who have something to complain about reach out whereas everyone who has everything going well isn't saying anything. So, in my opinion, you can stay to course (as long as it isn't killing you mentally) and I don't think the site is suffering any for it.
Is Kbin dying? I wanted to address the deleted thread and provide some insight into the current situation. (kbin.social)
