Take a break, seriously. There is a thing called 5 stages of grief, I won't go into detail since most of you know about it. Basically, you aren't cool-headed enough to do any more trade after taking a huge loss on your trade account. The more you want to jump back right into trading, to recover the loss, the more likely you are to make mistakes. Sometimes, you've to take the loss straight at your chest and need to move on. But of course, easier said than done.
