I'm glad you have a doctor on board.
Have you told him/her about this?
It really would be a good idea to make sure you are OK after yesterday.
That was a lot to do to your system, and I imagine it will take a little while to detox from that, so that may be part of why you are feeling shaky.
If you can, try to take deep breaths and drink water....
I know you feel bad right now, and I know from experience what it feels like to see a damaged car and know 'I did this, but I don't remember...'
For me, that feeling meant that I never did it again.
Sending you love. ♥
