I’m not nearly as qualified as your professional help, but there are always bright spots and safe spaces to exist when you’re low. Everyone is exhausted these days, and you’re not going to change the world by dedicating your entire life to worrying about it. Take what you can and fight for what you’re able to, but don’t overexert yourself. Ideally half the fight needs to be done by people who are not the minorities in question - these people have the most privilege and population to actually enact change. E.g., telling the homeless to fight for themselves is not how you end homelessness.
