It is easy to feel discouraged when yet another school shooting occurs. Please don't surrender to despair. I know how hard it is to stay positive, but we must. In the U.S. we are in the midst of an extraordinary power struggle, a struggle for the soul of America. It is a fight that cannot be ignored and will not go away. If we give up, then evil triumphs. Do something small to affect change. It will make you feel better.
Call lawmakers in your state, or those who represent you in Washington, D.C., and ask for them to vote for gun reform. The people answering lawmakers' phones are professionally trained to be courteous and take your calls. Be courteous in return.
If you are phone-averse, then write a letter. Send a postcard, or an email. Show up for a protest. Donate to your favorite candidate. Join a Facebook secret group to keep informed. Every little effort matters. Every one of these small steps is an action that will make you feel better about yourself and your place in the world.
Do not respond to trolls on social media. They are often not even human. Others are Alt-right provocateurs who are posting or commenting based on scripts they have been provided. Responding to trolls only serves to bump their Facebook comments up to the top, which is the purpose of their vitriol. It is best to ignore them.
Don't be afraid of failure. We must try and fail many times before we win. We only truly lose if we give up.
