Mischief in my head

Really struggling tonight and there is mischief in my head. It's like I know I'm heading for a fall or something major.
All day I've been dicing with danger. I've picked up knives, rope, tablets etc and my head has screamed as I've driven my car to pull out or drive off the road.
I've made my room as safe as possible but my head is spinning. I know it's going to be hard to get through the night in one piece.
Can't be bothered to ring anyone for help as they can't help me.
Just wish my head would shut up
