You sound a bit like you're suffering from exhaustion - physical, emotional, and mental. It makes every little nerve raw, and like your last one is constantly sticking out, waiting to be hit.

When that happens to me, it's a sign I need as much physical and mental rest as possible. I'll cut back obligations to the bare minimum, and sleep/rest the remainder of the time until things feel better. Now when I recognize I'm getting exhausted, it's usually just one down-day, but at times, it can be a week or so of minimal activity. It's hard, because it can feel wrong to do nothing, but letting a body and mind rest and heal, sometimes really helps.

Be gentle with yourself. There's a lot going on
