ADX,
For each trade, consider your stop-loss to be the amount of money necessary to ante for a chance at a winner. If you adhere to your stop-loss rules, then your stop-loss is really all you have at risk, so there's nothing to fear. Be perfectly willing to give up the amount of your ante every time as you enter an order, and you'll be OK.
Also, think in terms of probabilities and a winning percentage instead of 100% perfection. It's a natural law of trading that you will not be right every time; don't fight it. You say your system paper trades really well. For your system to work, you must enter a quantity of orders every day. Accept that you'll win some and stop-out some, but with a winning percentage, you'll be profitable over the course of the day.
Stopped-out trades are just an unavoidable normal cost of doing the business of trading. You can't run a business for free, fearful of every little cost, and you can't avoid something that's unavoidable. Just limit your per-trade cost to your stop-loss, accept that small amount of risk every trade, and move on to entering orders and making money. Don't hesitate to make money and feel great about it when your system gives you a signal. After a number of winning trades, fears and hesitation will subside.
I highly recommend that you read this book:
