Take some time to learn more about the overall technology behind Bitcoin and decentralized block chain ledgers. Any little bit you further to understand the underlying technology helps you ride out these drops much better. Then look into some of the new projects that are coming out and about through the block chain and crypto community. There's a lot of really neat stuff being created these days. Not all of it will succeed, but seeing what's being done with the technology can do a lot to give you hope in a bear market (even if you're like me and don't understand all of it that well yet).
In addition if you believe in Bitcoin as a technology you can take a little bit of spare money and invest a little more into Bitcoin while the price is low. This way if you've lost some earlier in this bear market you can get it at a much lower price now so when it raises you can average yourself better. Either way you end up with MORE bitcoin.
If you really want to get rid of some Bitcoin, try to buy something with some of your bitcoin rather than selling it at the market and "dumping it". That way you get something out of it, support adoption and learn how to actually use it better. You'll also make the person earning it smile too

. Alternatively you can try to donate some Bitcoin to a worthy charity that may accept it and do some good with it.
Don't let the market scare you; rather educate yourself, invest while prices are low or use some of it for something cool to help with adoption.
I'm still a relative newbie, so also heed the advice of more knowledgeable people here on this forum. Just don't panic; great technology takes a while to get mainstream adoption.
