One of the worst things about being crushed out of a position, is that typically the market soon adds insult to injury with a violent reversal that would have drastically reduced your losses or may have even moved you into a profit.
As painful as an account blow up can be, it also provides you with a great learning opportunity. It would be a mistake to try to blot the experience out your memory and move on. Instead, while everything is still fresh on your mind, chronicle the entire trade from start to finish, noting your reasoning and thoughts for your actions every step of the way. Once completed, write up a solution journal going back through those steps noting what actions you should have taken as the trade progressed with the info that was available at that time. Look for any insight or signs that were missed that could have helped you realize you were on the wrong side of the trade.
Also important, you want to go over your trade management to see where there were clear signs you should have pulled the plug much earlier. You can be fast and loose in a small account, but never in a big account that you don't want to lose. Your trading system has to include a fail-safe that will end a trade at a specified percent without hesitation. If you give the market an opportunity to eat up your account- it's not a question of if it will happen, but when.
You should continue to trade on a sim account to work on your trading corrections while you're taking a break from live.
While the losses are painful, the silver lining is if you can resolve your trading issues and learn from your mistakes, you can make it back fairly quickly as well. Plus, you now have all the tax write off deductions you need to apply to any future gains for a good while.
