I have found myself in the same situation you describe here on a fair number of occasions, most of us have I am sure. I don't know what the answer is, but I agree with the posters who have said you should take a break. In my case even though I may have run badly for a while I often make this worse by playing badly and trying to play too long to get back to even on a given day. This will, more often than not, result in further losses. Knowing when to leave the game is a very important skill in itself.
I also like running back through the hands I have played to see how often I have really been unlucky and how often I have lost money due to poor play.
Some things you can try are:-
1) Play tighter and try to get a few winning sessions even if you are not taking advantage of every +EV situation it should help improve your confidence as you will start to win again. I tend to combien this with very short sessions (no more than 30 minutes) as you should be able to retain good concerntration for this time. Try this for a week and the results often put themselves right and your normal style of play just returns naturally.
2) Drop down the levels for a short period of time for the same reason as above.
3) Post the hands and get some feedback on them
But normally you CAN just play through it, as long as you are playing well things will turn around quickly enough as you will make better decisions than your opponents.
Thanks for the reply, 'tis sound advice. I honestly feel I'm playing ok so I'm carrying on for a little while. I know my attitude has to be good and I felt I proved that to myself last night after having some idiot crack my aces calling a near pot bet on three streets with only a gutshot..I just laughed it off and continued to play solid poker. I didn't come home thinking I'd butchered any hands so that must be a good sign. This is opposite to a few weeks ago where I was making some mistakes and posted them for all to see..lol
The notion of taking a break is interesting - as if by not playing you can't get unlucky. Taking a break makes sense if you are tired, bored, fed up or de-motivated. While I still feel good, I shall carry on - but a potential break is only just round the corner!!
