i usually sit down and cry in the shower. but im lucky cause theres a rink near me that has open hockey everyday during the day. im the only person that shows up. i let in everything through my legs, so i just do drills all day keeping my stick on the ice. like butterfly slide across the blue line and back etc. i think the best thing you can do is focus on a specific problem at a time. keep situations in your head, think about them, think about what to do next time. i suck so you might be better off not listening to me, but goodluck.
for me i just watch alot of hockey when this happens. study if you will and try new things at my next pickup skate or game warm ups and try and introduce them to my regular bag of tricks. also the new equipment thing does work nicely!
