seconding looking into anarchism and smaller community/forms of government for alternatives of what could be, and socialist history to see the types of great governments the US has squandered intentionally to push the "capitalism is natural" narrative... HOWEVER, these are tools for collective action and dreams to reshape our unfixable broken system. great knowledge but not great for keeping yourself mentally healthy.
stay or get involved if you can with political groups in your area, however I find it beneficial as an american to stop looking at our government as a whole. especially in rural america it gets easier to remember that our local governments, despite being controlled by the big wigs, are more influential to our lives and something we can directly change. we can also touch people close to us, rather than focusing nationwide or globally. in these times it's best to build communities to resist any oppressive change that comes onto us the best we can, sure - but to also cherish the great silver linings we have with each other in the midst of all the chaos.
it's okay to turn off your TV and hang with friends and do/find personal hobbies for a bit. it's okay to also not feel okay with the state of things. it is irredeemably and preventably bad, and it's okay to be mad about the tough times ahead. but it's likely we have a lifetime ahead of us still. so if you're lucky enough to find joy in it, do so like there's no tomorrow - even though I assure you there likely will be.
I wish I could be hopeful too but I think it's a tall order to ask when a lot of preventable problems are being caused and perpetuated on a wide scale. and I do think its a little subjective and based on a gamble of the future. can we have hope if things change radically? for sure, in some ways. can we have hope if things continue without change? not really. not for me or my family, and not for kids growing up now. but even though oppression is barreling down on me and my loved ones personally, I'm taking it as a challenge to be loud and proud and remind everyone they can't pretend I'm not here and human. I hope you feel inspired to do the same.
stay safe friend you are so so important and I mean it!!! if you have access to even one therapy session a month I highly recommend it just to get these worries out.
