How do you stay optimistic while being bombarded with negative news?

Hi, I've been trying to be at peace lately, but I find it so difficult. I am not American, but I'm seeing Trump everywhere. Every day it's just news about him saying or approving some awful shit. I disagree with everything he stands for, and it's just like being reminded of the worst people in the world every 2 seconds. Even outside social media, people talk about him, and I wish this could just END.

I'm doing my masters in the US soon and... Everyone tells me I'll be okay, even my American friends. But I'm just scared, man. Should I just leave social media for four years or what? lol

How do you guys deal with this? Thank you

EDIT: Thank you to the people who overlooked whatever my political view are and empathized with the feeling and provided helpful advice. It's good to know that even if people disagree with me, they understand the overwhelming feeling. For my own mental health, I'll stop reading the comments, but thank you again!
