Hahh dude great post, I feel exactly the same :D I'm still alright cuz I've bought early 2017 (not as early as you though :/) but the feeling of missing a sell around 15k or so is just horseshit haha :D Long-term no worries, but my greedy self is just super sad cuz I could have been twice as rich :D

Also, I hate this type of messages, but you really might be interested in my post...I've trained 4 machine learning algorithms on twitter data (1.6 million of tweets) and then analyzed bitcoin tweets sentiment changes over last 6 months...srry for promoting my post haha but I honestly just thought you might like it - it indicates uptrend in the next months :D
