Oof I’ve been there. It’s rough having your worldview turned upside down. The lucky thing for you is that you’re not the first one to go through this.
I’d say before you go anywhere, try to understand why you believed in the Democratic Party in the first place. Books like Manufacturing Consent, podcasts like Citations Needed, or outlets like Fair.org can help. I think developing a critical lens for political media is a key step towards building a new understanding of the world.
Beyond that it’s important to understand that politics can’t be limited to how you vote. Change in the US has largely been a direct consequence of mass movements composed of well coordinated organizations. So, if you’re willing to put in real effort to participate and learn, join a member run political organization like DSA. That is if you’re open to democratic socialist political perspectives :P
This is true for board games as well. The classic example being Monopoly.
