Don't feel bad. I've done that my whole life. Even taking shoes off, I sit on the floor because I can't balance myself on one foot and barely can stand on two.
I had A Fl hwy Patrol take away my cruches (one leg in cast from hip to toes from drunk driver) and expected me to preform same tests. Local cop came by and reconized me, otherwise I was going in. 5 years sober at that point, swerved when my infant son vomited on me from car seat. State cop said I was "falling down drunk"
