Sometimes nothing will help. You/I seem so Card Dead even the undertaker will reject us.
Part of the continuing process of dealing with this, that I try to answer, is why is it I think I'm card dead? Am I really? There are certainly sessions where my 2 pockets can't be connected by anything other than they come from the same deck and thus the backs match. Those are 'those' days.
Other times I find myself just itching to get into the fray. This is my impatience at play, not my rational self. For me, when I know my impatience is high, I will open up a solitare game (Freecell is my fave). This diverts my attention away from that 'want' or 'need' to get into action, and at a glance I can determine whether or not I am interested in the current situation at the table.
Things to evaluate at the table are -1st, cards ( I could probably do without actually seeing the cards, but they are the first thing I see when glancing at an online table. -2nd, what is the bet, to me? - 3rd, what is my position? -4th, am I opening, or calling? -5th What does my HUD suggest about the players who are still to act, or who may have acted before me?
If you don't have a HUD, you might have watched harder than I like to. You can still answer those questions.
When opening in later and later positions, you can widen you criteria quite a bit. Stop calling unless you hold something with actual potential. Search calling lite here. Be sure that when you come into hands with less than optimal holdings you can give it up before it gets expensive.
Bottom line tho is that you need to determine whether or not you are really card dead, or if you are just not in the right frame of mind to 'Play'.
Edit add. Recently I have come to understand a bit better the concept of scared money. Scared money playing above reasonable BR mgmt will create a mindset easy to think card dead, when really it is being afraid to play.
