Honestly this is an amazing time to stock up and buy more BTC. Its definitely not going anywhere and I truly believe a few months from now we will be wishing we bought more at these prices!
Emotions definitely sometime try to take over, but try your best to remain emotionless ( you definitely need too in this market), use your best udgment and continue to trade based on what you can afford!
Do NOT panic sell. It'll all be ok in the end :D
