I am sorry you are experiencing this. I can experience a bad nite if I get triggered enough. I know what you mean when you describe waking up depressed and tired. Are you working with a therapist right now? Sometimes that can stir things up and cause a person to try to process while sleeping. The brain can tangle things up trying to figure out where to file things. It can be confusing and stressful which may require more therapy. Patience is very important when going through this. It takes time to sort out whatever is causing you to experience this.
