My poker (loser) experience

You obviously have skills to build a roll like that so fast. However, you obviously have some conflicts going on in your head that are going to affect your play regardless of skill level. You need to resolve those issues to play at the level you are capable of. Send me what's left of your BR for safekeeping. Either solve your problems or learn to put them aside while you play. I speak from experience, no matter how good you are, no matter how much better you are than the others sitting at your table, if you have things going on that cause you to make bad decisions, it will destroy your bankroll. Step away from the table.
