[3 minute hero]

I have been in the same spot and there is not much you can do but change table. However, i read somewhere (cannot remember where) that you should play a bad bluff and get caught - this shows you are not infallible - obviously not for too much money. Your opponents see a weakness, close in for the kill, you then play top starting hands and trap them. I think that was the way it was supposed to work.
I change table or play another table as well, sticking to my original game on first table, when people leave the new arrivals take a while to get settled and during that time they can lose money.
