Previous diagnosis before PTSD?

Just wondering how many other people have experienced something similar. It seems (from my google searches) that is more common than not. At a very young age I was diagnosed with ADHD and placed on meds because I was always day dreaming, forgetful, lost and confused. I have always had an imaginary world that I simultaneously live in for as long as I can remember.

I have seen a psychiatrist most of my adult life for med management for my ADHD but a few things have changed in my life and my anxiety was out of control. Started having panic attacks all the time for seemingly no reasons. Images that I had hidden way back started popping up and I couldn't get rid of them.

So I started to see a therapist. I was already taking meds for my ADHD and medications so I could sleep at night but have never tried anything to manage my anxiety outside of medications.

Over the past few months I started to open up to my therapist about things that had happened in my child hood and now terms such as disassociation, PTSD, trauma, are all being used. Im not sure what to make of it. Its beginning to seem that my ADHD might actually be secondary to some other untreated causes. Perhaps my insomnia from my repeated nightmares has more to contribute to my ADHD than actually being ADHD.

I guess this isn't really a question but more of a quandary. I have been thinking about things a lot and maybe too obsessively.
