If you notice the following actions:
Play more
hands than usual.
You often
bluff without good reason (both preflop and postflop).
Feel hopeless that you can not win a single bank.
Make bad calls on the river, knowing that you need to fold.
That chances are that you are in tilte. In this case, you need to immediately terminate the session.
Trying to keep playing with gritted teeth will usually be a bad idea for most people and can turn into even greater losses. You simply will not have a clear logical thinking, you will play C, D or even F-game.
If it seems to you that you are tilting, then most likely the way it is.
Cover the tables immediately. The game won't get anywhere from you if you come back tomorrow.
