When we devalue ourselves then things and people on the outside become relatively much more powerful and more significant. If we love ourselves - and you do deserve that - then they really don't matter. It's not that the world and life and events don't matter at all, but it's only a fraction of how it may feel now; it's a whole different perspective and experience. People have survived decades of oppression, prison and worse on that basis.
Turn off the social media and the news if it will help - that stuff is not important; you are. I could care less about all this stuff on HN if you, a real person, is ok. And talk to a professional, a therapist; you don't have to feel this way and it can change your life.
I really hope that helps you some.
