I need help for puck-handling?

I have a problem with my puck-handling. I'm a goalie, but this winter I'm going to play and I might switch and play forward also. The problem is that I'm having a hard time handling the puck (I'm a sniper I usually shoot on p reception). When I try to handle the puck, it ends by me losing the puck (going far) or my blade touching the top of the puck constantly. So what do you think is wrong? Am I holding the stick too tight? What can I do to improve it? Thanks.
