Lots of encouraging advice here.
I would recommend you to take a walk outside. While out think about taking two steps forward and one step back. There are always hard moments in life for all of us.
Remember that you're not alone in this. Anons and whitehats are fighting for the better of us all.
Excercise, healthy food have been mentioned. Taking care of yourself is good for both physical and mental health.
Also if you're religious, try to seek out Jesus (personally I'm not that religious but it might help you out!). Go to a church or read the bible. God wins, after all.
Take care of yourself and maybe focus on a hobby. Don't delve too much in all the evil in the world. We all do our part to better the world and there's no need to take all that weight on your shoulders alone.
