Living in the US is an absolute nightmare

I’m graduating with my bachelor’s degree in 3 months. My life’s dream, everything I’ve been working towards, is research. Research that might not exist soon because no one knows what’s going to happen to grants and funding if DOEd goes away. I don’t want to start over in a new country to live my dreams. I don’t want to leave my friends, my family, the love of my life behind and start all over on a new continent. I can’t do it. I’m terrified I’m gonna have to choose between living my dream and leaving everything and everyone I’ve ever loved behind, or stay here and never feel like I lived my life’s purpose. I don’t know what to do anymore and I’m so scared.
