Trying to Deal with Flashbacks

Have a nice weekend? Now, back to the global grind.

Mood swings are still there. There's a feeling of emptiness and seeing key things flash in front of your eyes. People and places where you see it, but you feel sad because there's nothing you can do. Eiher to help them or nobody seems to care to help you.

It's not a death wish in any way. Maybe it's more of a feeling of not wanting to literally be cheated out of any happiness at all? Is this a common thing for all survivors?
