Jimmy,
We've all been there. Try reducing share size to rebuild your confidence. Go down to whatever minuscule level it takes to be carefree (not careless). For me that was risking $25 a trade.
Trading small for a long enough period of time will develop the good habits and reduce hesitation.
Once you find yourself entering, managing, and exiting without fear, slowly increase share size. The trick is to make it so gradual that your psyche won't know the difference. This strategy allows you to risk more--and make more--as your consistency increases.
Cheers.
