Gaming is an outlet of mine as well. Keeps the darker thoughts at bay. Though I was lucky and only get the occasional nightmare from my time in the sandbox. I get where your coming from, just always keep in mind bravery is not the absence of fear. It is the absolute presence of fear, yet the unyielding will to persist. There will always be pain, death, and suffering for as long as there will be humans. It is each persons own responsibility to seek whatever comfort and happiness they can find, despite the woeful state of the world around them. If you seek peace in the world, the best place to start is to find it within yourself. Cure yourself, then cure the world. And if you think one person can't change the world, just look back at human history; just one person is the only thing that ever has.
