We've all been there, including me, many times over. It's how we learn to not make the same mistakes in the future. Too many people fail to post their losing trades and we never get to discuss them. I wish Sponn had posted the trades that blew his account but unfortunately, he didn't so there is no way to fix that.
I have a great deal of trading experience and you know how you get that? By screwing up. You get experience from learning from your mistakes and repeating them less frequently. I say less frequently because we are all human and we will make mistakes in the future. The added experience comes when you see the same setup again and your reaction to it.
When I make I mistake, I generally throw the trade away as soon as I see my mistake. I never marry my trades and I learn to make my bad trades more profitable to me by doing this. This is some of the experience I gained from screwing up.
