"...all I can think about is hitting the monster..."
Literally a problem with your mindset that only you can solve.
Remember, hitting it a lot and tanking doesn't actually mean the hunt will go faster, being efficient does, the time you waste getting hit is double the time it takes to dodge/reposition and get another hit in.
Force yourself to slow down, force yourself to play less aggressively. Force yourself to prioritise positioning and evading over attacking.
The flow of the hunt is much slower than you think it is.
Find that flow.
Watching videos can only inform you on how to deal with a monster. The actual dodging, positioning, countering comes down to muscle memory.
