Go outside and focus on one thing: greenery. Every time you see it, smile -- and you'll find yourself smiling more than you think.
At the end of the day, like hinted in your question, it's all about perspective. Let yourself feel the feelings, but know that in the grand scheme of things -- all these issues are breaking down so people like us, the optimists, can take inspired action to create better solutions that serve society today and thus inspire more positive action to be taken by those influenced by our actions.
Hope that helps <3
