Yep I've been there more than once, the 911 crash killed me, back then we only could move one time a month and I got out at the bottom and had to wait a Month to get back in, I lost over $10,000 dollars. A learning experience, if you are down that much just hold it will come back slowly and sometimes rather quickly.
Oh gosh that is a lot I'm sure that hurt. I didn't lose that much thankfully.
Let's hope we rebound Monday.
