I have no doubt that the decisions you have made with your bitcoins have been based solely and exclusively on emotional impulses rather than on an adequate analysis of the pros and cons, risk-reward ratio and other more financial analyzes.
Unfortunately, the laws of money seem to be efficient in rewarding those who show enough intelligence to administer it, and punishing those who do not take care of it and administer it properly.
Therefore, I hope that this bad experience will leave you some teaching about it, and rest assured that if you try hard you will always find new opportunities to recover your lost money, and even multiply it.
I am agree with you. People sometimes get emotional when they see price rally and they want to jump in. But i think its experience that we can learn. Its happen to many peoples including my friends but he still keep hold his bitcoin for long term
