Depression/Anxiety post concussions

I have had 2 concussions within a 2 week period. CT scans of my brain were negative, however my cervical spine was quite damaged as a result of one of the falls. My cervical lordosis is completely reversed. The headaches are extraordinary and I have been advised not to take anti inflammatory medications because of my liver/pancreatic disease. also having an increase in depression and anxiety as well as some cognitive problems, primarily with reading and spelling. I am advised to rest more, which is not how I am wired. I am also told that post concussion syndrome can last for months. This is the last thing I needed with everything else going on with my dilated liver and pancreatic ducts. Can anyone offer me some sage advice on how to better cope with my symptoms? Thank you.
