Don't worry worstEMTever (that name is funny),
I've moved pts with the foley still clamped to the bed, given another a concussion on a backboard during a bumpy transport(no head cushion-whoops!), and accidentally punched another pt in the face!
I have also pulled the stretcher with the NRB mask still attached! my last episode I gave "Cricoid" Pressure right on the Adams apple!(needless to say we intubated the stomach twice and we had to cram a rescue airway down pt's throat!)
The point is, after 2 and a half years(still green), I have learned that you have to let s@&* go, learn from your mistakes, and move on.
You will be ok if you do that
