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. 
You made a good decision, imagine if you were still hodling, not only you'd lose even more in bitcoin, you'd also suffer opportunity cost from missing out on interests, dividends and returns from other investments.
Your friends were right, they cared about you and must have been concerned about your mental health. I'm glad you woke up and got out of the cult.
