I can't stop catching random bugs going around. Right now there's one sending everyone running in the bathroom to vomit and shit everywhere.
I know if I catch that I'm out for a week, minimum. But so far, so good.
My issues are strictly IBS, thankfully, so I keep careful with my trigger foods and try to keep my anxiety in check...
But I'm still like you, these winter months grate on me terribly.
I live in a northern climate and we've had almost no snow, which triggers my anxiety a bit, even though it's not in my control.
But I love the snow, so having no snow but still little daylight FUCKING SUCKS.
