+2 to heckler and nereo. Your statement doesn't make sense, you feel you are under weighted in equities and your solution is to shift more towards bonds? That's backwards, something must be missing or you used some wrong words.
Make an IPS and stick to it. My 401k has a re-balancing option so I set the % I want in each fund so it remains consistent with my IPS and it automatically rebalances for me quarterly. I don't even look at it. The rest of my investments I look at on my birthday in January, and I rebalance them back to comform to my IPS. A slight amount of math involved, but absolutely no thinking or emotion. All the emotion was factored in when I made my original IPS. I picked what I would be comfortable with long term, and now I am sticking to it regardless of what the market does, I will only be rebalancing on my birthday each year.
