It seems every time I find something that looks promising, I'm just a sucker waiting to give someone else a payout. I have been following advice a gentleman offered to "hodl" my bitcoin, from $984 all the way down to now $436. I've just been fooling myself, telling myself "Don't worry hon, it will go back up! It always has!" I've been spending my time reading the forums and hoping. My friends called me crazy when I told them it's a sure thing. The shame is just as bad as the lost money. So I quit. You guys win. Coins sold. 
all the people that bought on top of previous bubbles felt the same pain you experienced. the ones who resisted and did not sell are very happy about it now. a theoretical loss of 50% feels ugly as hell, but a realized loss in an asset, that came back to new ath may turn you in a hateful person.
i started to get involved in btc in 2011, but i really put in almost all my money in may 2013. a few weeks after my move the price was down more than 40% - i felt so stupid. i will never forget how it felt. the only reason i did not sell was, it was such a big loss, i just didn´t have the guts to realize it. i still believed in the superiority of bitcoin, and i still thought it was a great invention but i learned that those things may not matter when price is going down anyway. when i invested i was so confident about it that some people around me also started investing. being the reason for their loss made it even worse (they are rich, so i knew they weren´t hurt, but i was anyway ashamed)
but then came september, october, november...
you somehow managed to get through the (hopefully) bottom of 339. why give up when we could be behind the bottom ? i really know how you feel. i would buy back at least 30 % of your coins if you do not need the money desperately and wait a year or two. be prepared to lose it all, write it off in your mind.
there will be another november. the bitcoin economy is so much bigger than 12 months ago. all this gox/china/ fudquaketsunami will be over with sooner or later.
i would really like to invite you to THE PARTY when it happens....
