I suggest if you are playing that level ask a peer or pay a coach to review some of your losing sessions so you know for sure if its run bad or play bad.
Remember you are playing against a range of hands and not the nuts, don't skip on the mental effort of ranging your opponent.
We know that run bad and run good happens as standard in this game because the margins are so small.
Coping with the run bad is key as my coach points out regularly.
