I’m 29 and angry but to a point of hopelessness.

One of the Kennedy descendants was on the radio earlier saying that "the antidote for cynicism is activism". There's plenty of ways to get involved and you can chose your level of engagement: Greenpeace, JSO, Extinction Rebellion. We can argue until the cows come home about the effectiveness of activism but CND certainly helped keep the issue of nuclear disarmament at the forefront of people's minds until the end of the Cold War (and beyond), which I think most people would agree was important.

Sometimes I have conversations and there’s only me that seems angry so then I doubt myself.

Perhaps what you should be doing is shaking them out of their apathy.

Then I wonder even if I wanted to change anything what could I even do, it’d be just as productive screaming at a brick wall.

The only guarantee is that if you do nothing it won't make a difference. Collective action relies on numbers.

The countries fucked and at this point I just hope I can keep feeding my family long enough to make it to my grave naturally.

But then what about your kids? You may get out before it gets really bad but they will see flooding and desertification displacing huge numbers of people with knock-on effects everywhere (political instability, wars fought for resources, etc, etc). Will you be able to look them (and possible grandchildren) in the eye and say you did nothing?

And then your family can get stuffed? It's amazing how many people with this 'not in my lifetime' mentality have kids.
