I agree completely. Your brain and overall health are more important than another year of football. I am a teacher and I see too many kids taking risks that they shouldn't. The adults/coaches around you should know better, but don't wait for anyone to help you. You need to help yourself! All of us understand the symptoms you describe because even if we get injured in different ways we often have similar symptoms. We " get it". And we all know how miserable it can feel. But many of us also know how great it feels to finally get some help and see some improvement. Get help. Do what mark says to do.
