Stress seriously magnifies concussion symptoms and prevents proper healing and recovery. Your anxiety is not uncommon. No simple concussion will ever show up on an MRI. You would need a more serious injury for the MRI to show it.

Your options are, Take time for quiet rest and recover as soon as your brain can or continue at full pace with work and school and take months to years to recover.

Water exercise can be much less stressful and jarring.

You do not say your age. Hormone changes in the teens can magnify concussion symptoms.

Minimized screen time and especially smart phone screens and texting. Too much stress.

Read the Vitamins sticky at the top. You need to help your brain tolerate stress and purge from injury and stress toxins.

My best to you.

Thanks so much for the information. All this new information is a little scary to me, if you can understand. It seems like everyone on here has a horror story. Joining this site is either going to be very good thing, or a very bad thing in terms of anxiety. School's school and that's going to be constant whether I want it to be or not, but I'll try to see what I can do about work. I respect each and everybody's advice, but I'm going consult with a neurologist before taking these suggested supplements.

Thanks
