First, I feel your pain, but I believe it is being diseminated with intent. Social media and psychological influencing is new to us of the elder population, and we are obviously more susceptible to its impact. I would recommend you refocus on yourself, your family, friends and your faith. Stay true to your personal beliefs, and the things that bring joy to your life.
Everything is cyclical, nothing remains constant except for change. The overall health of the economy always leads to changes in political power, and this economy is ripe for another adjustment. Social issues usually take longer to illustrate their negative impacts before the shift in attitude happens. We will see the adverse effects more clearly 20 years from now, and those that maintained a moral and ethical lifestyle will be all the better for it. A lot of DNA is being voluntarily removed from the gene pool as is a product of natural selection, and that is a remedy in and unto itself.
Politically, you must see the corruption across the board throughout our government as well as the permanent and distinct divide. Choosing Right or Left will not improve the political climate this election. Both parties are entrenched and have clearly illustrated that fact, so the best immediate alternative would be a 3rd party although none has ever truly been relevant.
I'm older with my children almost all being young adults now. They as well as their peers are intelligent, morally upright, somewhat financially conservative and all seem to be enjoying their lives while looking forward to what the future will bring. They do not see our country and the world from such a cynical point of view as we do. They offer a great place to garner a bit of hope and optimism from.
Last, I would recommend spending some recreation time reading and watching historical periods. They offer great insights to the ups and downs of societies throughout time. For the most part regardless of the atrocity, humanity has endured and improved.
