During crisis situation it is very important how is your conduct. With the right conduct you can manage any situation and come out of it with flying colors.
If you break during crisis, you will be a subject to handle for others. In this situation neither you are helping yourself nor your environment. Rather you will putting more loads on others.
Be a solution to the part of a bigger problem. If you cannot do much, just ensure that with your right conduct you handle yourself well and do not create any dis-harmony around yourself.
You cannot fix everything around you, if you just fix yourself lot of things will be taken care. When there is not much to do outside, work on yourself. Ensure your action and expression to the situation is appropriate and helpful.
If you just manage your conduct well, many of your things will be taken care on its own. Try it out, you will see how easy few things are!
