How to deal with the grief of the world?

I have a long history of mental heath issues and live in the USA. I feel like that's all you really need to know to understand where I'm coming from. Everything is messed up. Everything. Is. So. Messed. Up. The government is killing innocent lives globally. I want to go somewhere peaceful and I don't even know if that exists anymore. I'm just stricken with grief daily, all I seem to be able to do is cry in bed these days. What on earth can I do???? I'm so exhausted.
