You can be much more effective if you are clear-eyed and calm, rather than being freaked out. By calming down, you will be better able to practice the patience and skillful means necessary to help change this situation. By calming down, you can better channel your anger and fear into positive skillful action. Change doesn't happen overnight - unfortunately. If we want change, we must create the causes and conditions to bring about change.
I understand your negative emotions. Right after Trump won the election, I had thoughts for weeks about eating my pistol, because I'm a senior with heart disease, who depends on medicare and social security income. But I am beyond that now, because I was able to calm down and get a grip.
I heard John Lewis' MLK-day speech, and it really inspired me. I still sometimes shed a few tears when I recall it. You must have faith that "the arc of the universe bends towards justice." I promise you that the current Republican kleptocracy will not last forever, because nothing lasts forever. The questions are: what change can we bring about and how soon will we see the results of our efforts. There will be setbacks and obstacles along the way. But we must create the causes and conditions for the changes that we want in the future. There are millions of people in this country diligently working in an organized way to turn this nightmare around. We are not powerless. Get involved with your local county or city Dem club or join your local indivisible group and work to create the causes and conditions for change. Work to elect (or run yourself) local city, county, and state elected officials. Get involved with your kid's PTA or your church group. But find something that is important to you and get involved. Stand up! Speak out! Make waves!
Listen to John Lewis MLK day speech, and see if it lifts your spirits too
