Soccer 14,

A concussion can cause PTSD to be more pronounced. They work against each other to create a combined cluster of symptoms worse than either alone. But, PCS alone can also be the cause of all of your symptoms. The tragedies you have been close to just create a heavy emotional/stress burden when your brain is least able to tolerate it.

It sounds like you could benefit from some counseling therapy to help you with these issues. Your emotions may be flat but your mind still needs to process the events. Maybe a doctor specializing in Physical Medicine and Rehabilitation (Physiatrist) can refer you to someone who understand PCS, grief and even PTSD.

If you are anxious about his brain injury resulting in death and comparing it to your own head injury, you need to realize that your injury is long past the time when it could put your life at risk. You are not even at risk for Second Impact Syndrome.

It sounds like your classwork may be a bit stressful for someone with your history, at least in your present state. Pushing through stressful events and classwork is counter to recovery.

btw, What are the symptoms you have that coincide with PTSD ?
