PTSD is a very complex problem and cannot and will not be fixed overnight. Embrace the process. Embrace the ups and downs; use this energy to heal yourself. When I feel up, aka anxious, I like to use it with my art or exercise. Sometimes I need to talk it out with a loved one.
When I feel down, I cry and I mean I cry. I let it out. I don't even need to know why anymore. I just reach far down where the pain is at and release it. It feels so empowering when you can express the pain in moans and groans. It's more powerful than you can believe. God hears you!
