With all the negative stuff going on (Trump's failed assassination) and everything, it is natural to get absorbed in the doomerism. Of course, pretending that nothing scary is happening isn't the best thing to do. Scary stuff is happening, and we need to take action.
That being said, I personally trust Americans to do the right thing. Trump won't win, and America won't go fascist. This is because good people will fight and win. Same goes with other countries (France and the UK for example).
Leaving politics aside, there's a lot of hope ahead. Science and Tech is advancing, life expectancy is increasing, investment in transit is increasing, countries r going greener, etc. Many cancer therapies r coming out (see the cancer vaccines for instance). Many cities have done some much needed land rezoning, due to which affordable housing will be a thing, 15 minute cities will be more and more common and so on.
The future is looking good, exciting stuff is happening and EVERYTHING WILL BE ALRIGHT.
Again, a little fear is good. Fear is what prevented early humans from being killed by predators, and it is what will prevent bad things from happening to us in the future. However, letting it consume our lives is a little counter intuitive.
