What are some of the best methods you've found to feel emotions less intensely?

I used to be very empathic, I cared so much about the world and everyone in it. Making sure people were taken care of, and hoping for the best for everything. I would get depressed when bad things happened and I couldn't do anything about it. But as I've gotten older and the world has gotten so much worse and it keeps getting worse and worse. I find I've adopted an "It is what it is" attitude about nearly everything. I have zero faith in humanity and it's ability to over come the downward spiral we are in, and doubt we will still be here in 100 years, and frankly have gotten to the point were I feel that might be for the best. Time for the universe to hit reset and start again.
