I don’t think I am in the position to say this, I’m not over sadness, anger, and whatever negative altered state of the mind.
But there’s one thing I eventually figured out.

Life is a complex thing. It’s a mix of good and bad news, and you can’t avoid the bad ones. In fact they are part of the journey.
Living through the bad news is part of how we define ourself.
The choices we make based on our reactions will change us deeper than we think.

This is life, it’s not an easy game, it’s not a game for everyone, and it’s easy to feel lost, because no one can give you an advice.

Personally I always try to use the worst case scenario to put things in perspective.
For example: compare the bad things you had today with the war, the dying of all your dears, a natural catastrophe.

Your daily bad news will likely seem unimportant, and in fact they are unimportant.
In 10 years from now these fight will be forgotten, this moments of anger won’t be remembered.
