Of course, the obvious solution to coping with trauma is usually therapy, and that can and will help. However, therapy is not always a viable option in times of stress and trauma and many people for whatever reason are left to find ways of coping almost entirely alone. Something that has worked for me reliably in the past is seeking information. That means going into my personal space where I feel physically and mentally safe and comfortable (this can be just about anywhere, depending on your needs) and turning to the internet. The best way for me to cope has always been through learning. I get as much information as I can about what might've caused the trauma, what stage I'm at in the coping/grieving process, and productive ways to keep going from there. It's not so much the goal to understand what went wrong or why, but to use it as a building block to to elevate myself back up. There is a massive archive of self-help books and blogs written by people whose situations aren't going to mirror yours 100%, but they don't need to. You will learn to realize your own patterns, tendencies and mistakes. You'll begin to understand and accept yourself in a way you never did before. A lot of recovery comes just from knowing you are not alone with your pain. As you begin understanding more about the situation that caused you trauma, facing it head on and reading everything you can get your hands on about similar events in other peoples' lives, the trauma will have less and less power over you. You'll feel strengthened, supported by the vast network of people who have gone through something similar, and enlightened by the experience rather than letting it destroy you.

This got long and preachy. Sorry! This process may not work for everyone, but it definitely helped me massively. Hope this helps.
