If the feeling is only in regard to working on the kilt, then I'd recommend that you put it aside and begin a project that you really want to work on.

If the feeling has crept into other areas of life, you might be getting a little depressed. That's not at all surprising or unusual considering what's happening in the world these days, even if it's not affecting you directly.

I think my point is that you should take your feelings seriously. Even if you think you're just being a bit cranky, there's a reason for it.
