Burn-out?

I think this is pretty close to how I feel.

My energy-level has been low for a while, I have had very little concentration or focus last few weeks, or maybe months, I don't know. Now I ran out...
To be honest, I've had my mental breakdown last Wednesday, tried to finish my week and call in sick on monday, but that didn't work out at all...
So I've had my second breakdown yesterday and am I officially 'non-active for an unknown period.'
Tomorrow I'll see my doctor. For now, time to sleep.
