Welcome to the forum and to the world of head injury in the UK. I had a fall in January and received a similar piece of advice from my GP. From my experience in the UK the Dr's are quite dismissive of long term head injuries unless you have had a really obvious head injury (fracture skull) as they feel it should clear up in a couple of weeks.

At least your GP seems relatively sympathetic - I saw my new GP yesterday because I was starting to feel like I was developing tendencies towards seizures. Rather than explore what the symptoms were, he looked at my records and suggested migraine tablets for my headaches to go with the paracetamol and then ushered me out!

If you can stand some screen time have a look at these UK based resources - there isn't available and Headway would be a good starting point
