This is normal for greedy gamblers. You get more excited to bet when you’re in a winning streak, I think everyone does. The problem is, due to your overconfidence that you will consistently hit a huge amount, you tend to lose control of your funds, until you end up realizing that all your profits have turned into losses already, and you can’t do nothing about it but to regret and blame yourself, wishing you immediately cashout your winning amount. At least you learned your lesson as well.
