Post Concussion syndrome - Anxiety?

I've been diagnosed with PCS (Post Concussion Syndrome) and have been suffering from it for 5 months. Recently in the last 3 or 4 weeks or so I've been having Panic attacks is this normal and is there anything to help?

I also suffer from PCS, though I'm into my 7th month now. I have also had anxiety attacks which are worse as time progresses. I find the only thing that helps is if I tap my feet or twitch in someway to release my energy. I have to talk to myself and walk it out. I never used to get stressed or anxious about anything, but recently every small thing has been a trigger. So I don't think this is uncommon, my doctors have mentioned that anxiety and depression relate to PCS. I hope this helps you.
