I know, it's a strange question.

I have a personal and family history with anxiety but nothing close to needing medication.

After trauma to my head, my problem was anxiety and all the symptoms associated with anxiety. Over the following months, I suffered from a few panic attacks and intrusive thoughts. While those have subsided, I still have all these horrendous anxiety symptoms that I can't shake. I almost feel like the trauma changed me on a sub-conscious level where the anxiety is now automatic, or can't be suppressed the way I could suppress it (or deal with it) pre-injury.

Post-injury (1-6 months), I found myself freaking out trying to rationalize what had happened and what will happen in the future. I became fearful of everything, even getting through the day. And to this day (11 months later), I find myself having awful symptoms from sunrise to sunset. However, it's after sunset that I start feeling much better. And it's because of this that I now go to sleep at roughly 3AM and wake up around noon. It's a vicious cycle I can't break.

Thoughts?
