Agreed.
You can do this day. Even though you may feel you can't, in reality, you can and you will. If you don't believe in your ability, listen to positive voices here and in your life that are lifting you up and on throughout your day.
Less then twelve hours, I was cursing my thoughts that wouldn't stop or let go. I felt like I couldn't even get ready for bed. I realized arguing w myself was making everything more difficult. I struggled through simple grounding thoughts. As I brushed my teeth. And on. It was a battle, but I completed my day and woke up to a new one.
When I say that you can do this, I am not necessarily saying it will be easy. But you can do it. You can get through the flashback, brush your teeth, keep breathing, put one foot in front of the other, call a therapist or trusted friend or family for help, post updates here. In spite of the pain, fear, and trauma, You can do all these things and so much more.
