hi there,
glad to see you making your first post as well
sorry to hear about your difficulties. but i hope you realize now the importance of bankroll management to keep from going bust when variance is not on your side. it is practically guaranteed that you will experience bad beats. this is the nature of poker, and part of what makes it exciting. it is a familiar feeling for me, as there has been periods of time when AAs, KK, AK were losing hands for me. losing with them 12 times in a row may seem unlikely but are absolutely possible actually.
it will be a little tough to play with a $12br since you will have no comfortable cushion if bad luck hits you (or you go on tilt and misplay some hands). i think your best bet would be to go with the lowest variance games like roo has suggested. 6handed and esp HU can be really swingy.
i also suggest you to really study up on your game to make sure that you are not making many mistakes. how about you read some articles and watch some videos first?
when you are tilting, take a short break from the tables and breathe.
make sure you are focused 100% on your game and not chatting/checking emails at the same time.
lastly, forget what you have lost. there is nothing you can do about it now. instead, focus on what you have and accept it, and start working with it. i mean, the 50 was free right? if you thought from the beginning that you were receiving free $12, you wouldnt be sad about that, right?
rough times like these are really important in a poker players life in my opinion because they force us to look at ourselves closely, realize our mistakes and hopefully improve from there.
oh my this has been such a wall of text. hope it helps you.
smiles,
wendy
