Having hope is work sometimes.
A good way to get it is to start protesting, volunteering, or organising. There's a Catch 22 there. You may need to fake it until you make it.
If you can't do it on your own, get a friend to tale you. If you can't do that, I'd suggest finding a hopeful film or book or media.
And if you can't do that, just be careful of where you let out your doom. Don't discourage other people's hope.
It'a ok to feel overwhelmed by doom sometimes, but its not a good idea to live there.
