Scared to move up - whats wrong with me??

[Alex424]

Hey Guys, Been playing seriously for about 18 months now and am a winner at 3/6. The problem i have is i'm scared to move to 5/10. I have tried on a number of occasions now but always end up immediately having a bad run of cards and i end up bottling it and going back to 3/6.

I have a healthy bankroll but am worried about undoing all my hard work at 3/6 and having a sick run. At 5/10 the money is starting to get serious with major swings (for me anyway). I can't seem to get past this. I never tilt (i really don't)- probably my best trait in poker, but having swings of hundreds of dollars daily is making poker into a nervous miserable experience.

You may ask why i dont stick at 3/6. well i want to win serious money and my game is definately solid enough to win 5/10 and probably higher.

Any help is appreciated
