You've experienced your emotions overriding logical decisions for the first time, and you FOMOed into a trade- that's a good thing to realize, and that's something you'll need to get past if you ever want to become successful in trading. Most emotionally driven decisions you'll ever make, including and outside of trading, are generally not good decisions, and though it can be tough at times, always do what your analysis tells you or ride things out 'till the risk/reward of a particular scenario is no longer worth it. Not every pump follows through, and not every dump follows through either. That's what makes trading tough, and in this case you were greedy and didn't close out when you knew it was right.
