"A new low "

The GP (Dr. Cannot be named) clearly thinks concussion is least of seriousness/ importance category since the "afternoon" appointment (phone call) was last on his list just 30 minutes before home time/ clinic closure at 6pm. The appointment felt more like an arguments and less like practitioner trying to help. Remarks like " but you don't have brain damage", " concussion is something football /rugby players get". Doctor was clearly unaware that I've been to A&E or am currently not working as not fit for work, despite having all records available in front of him. Not professional at all. Felt like I was being gaslit. No passion for his profession at all or willingness to help. Been told to seek help elsewhere but it's up to me. Shocked doesnt sum this experience
