A person with leadership skills can still benefit from experience.
My current company is lead by someone with good leadership skills, and successfully managed a commercial team. Now he's trying to lead a company, and it is clear that he does not have the necessary experience to make the correct decisions.
> which i refused to learn, since i already know javascript. once static type checking became a requirement in front end is like the intersection for when i became a dinosaur.
I doubt you are a dinosaur for not learning Typescript. You should be able to pickup Typescript if you are motivated, but that is hard to find when you are depressed. From your description it seems that you have all the background skills necessary, even though you have not had the energy to keep up with all the latest trends due to depression and other health issues.
As others said, you need to work on the root cause (maybe burnout or depression). You should contact a professional to help you manage this and get your energy back
