You weren't thinking you were greedy and you were only driven by desire. Probably because you are playing with more then you can afford.
My recommendation is to sell during the weekend, where this "reversal" will probably peak again. And then leave it be until everyone else are in tears, and then only start considering buying back in. You will have plenty of time since it will rest after the bottom is reached.
During bull markets, then you have to watch out for being trapped with FUD. During these bear markets, FOMO is your enemy and the majority of traders lose because they were caught in FOMO.
