If you don't mind answering, how big was your loss and how lenient were your stop losses... if any?
I assume you were long financials or anything for that matter today... All I can say is don't attempt to pick bottoms. If you like Livermore, follow his advice about not going against the trend or fighting the line of least resistance.
Look at a 90, 60 and 30 daily charts.. Its extremely bearish and you are fighting a steep slope down. I'm sure there will be dips and ultimately a reversal, but why bet on them. The higher probability trades are short.
In terms of psychology, major losses will surely effect you and may make you "revenge" trade or trigger shy even. Your best bet is to trade small now. Regain your confidence and then go bigger.
You should probably just be honest with your wife too. Trading is high risk and dramatic losses occur frequently... even for the most talented professionals. She should accept that risk. She may encourage you as well. Just trade small initially though.
