the more days the bitcoin price slumps down, how do you think, whether the price will stabilize or it will keep falling down ,, seems like I'm getting scared 
I prefer to be calm than panic because if you panic then sell the assets you have at a low price it will only make you get a lot of losses, just wait until the price back up and patience is your key.
Well panicking will never give you a good result to your life. Just become positive that soon it will rise again.Hold your bitcoin until it increases because you might regret if you sell it at this price.
Being positive will always leads you to the right way in life. Bitcoin is like a person that is so important to you, when you encounter some challenges, will you give up on it or you'll be calm and become positive that soon everything will fall into their right places. We cannot predict what will come to your life to test your faith but always take that everything has its reasons ,just keep on holding on.
So be one of them that never give up on what they have, just stay calm maybe tomorrow it will rise too high again.
