It happened to the majority of people here..it happened to me in July...
Now the price is 6800-6900..so there is no difference than your selling price..
It is hard to predict the price.. but I suggest you to take a few days off and cool your head even if than means that you would buy later at e.g. 7200.  It is easier to calm down when you are not invested.. and than you can come back when you have clear head and stronger hands... you will be better trader and that is longterm worth much more than possible loss of few hundred euros per bitcoin..
