How much of a risk averse wuss am I? Won't move up to 10/20....

[IlliniRyRy]

I've been playing online for 3 years or so, played 1-2 for about a year, moved up to 3-6, did very well there, played 5-10 for most of the time and did well, built up about a 40k bankroll and gave 15-30 a shot last year, where I made 5k and then went on a 7k losing streak, then I quit and went back down to 5/10 6max, where I've been ever since. I now have 60k in the bank, but I'm still scared about dealing with the swings in the 10/20 6max. My bb/100 is probably only like 1.5 or so, I haven't kept track in awhile because pokertracker is so labor intensive, but most of my experience in the 5/10 6max has been pretty frustrating, even though I've made a very decent amount of money over the long haul. Am I a total wuss for not giving 10-20 6max a shot, despite the large bankroll?? I just get so caught up in the variance sometimes, I think I'm starting to deal with it much better lately, but it still bothers me. It doesn't adversely affect my play, just my level of happiness. Anyone here as risk averse as I am?? I need some encouragement. If I'm only beating the 5/10 by maybe 2 bb/100 at the most, I'm going to go through hell at 10-20 aren't I? I'll grow as a player, and I can certainly withstand the losses financially, but I'll be totally depressed. Then again, maybe I'll rock it, so is the reward worth the risk? Help!
