Nothing is lost if you have not sold anytime yet. Now, why are you stressed out with the losses, firstly, why are you selling them at the low price? Think what you should have not done. At least you will know where you fell so you know where to pick up your self. Secondly, as has always been said, do not invest at the amount you cannot afford to lose. Use extra money, better if small extra money then you your profit to re invest and so on and so forth.
