These are the rules of the game. Just accept that you are unlucky or that you shouldn't have done that, decide for yourself. But they hope that here they will tell you that you are a fine fellow, this is unlikely.
Nice comment! Leverage is pure gambling, and you are 101% right, the OP decided to place a very risky bet and he lost... it would be the same if he decided to play any other gambling game! When you are gambling and risking you need to be ready to lose!
With that said, don't do something you can regret later! What OP can do now is to try to not make the same mistake again... that works for others, try not to make this mistake, to go all-in with everything you have on a risky bet!
