I just stop looking at bitcoin price. It hurts me actually, that's why I took this decision. I am holding few of BTC and I will not look at my wallets too for 2 months. I hope after 2 months when I will go to see bitcoin price, maybe I will scream happily. What about you guys? 
If your interest is in the long term, as it should be, then this is the better tactic to take. Look every now and then, not every day or every hour. If you're planning on buying more, then of course you would need to look more often. But as is the case with a number of people, you're looking for the long term. And it sounds like you have a sizable amount, so I'd hold off on looking for a while for sure.
