The brain can memorize a concussion response and cause some of those symptoms to manifest from just the thought of "Wow, did I get another concussion?" This is even more likely when the person is already prone to anxiety or is stressed. As I said, stress put the brain on a hair trigger.

I see. Can I do things like smoking cigarettes, drinking caffeine, drinking alcohol...

You can do anything you want. But, if caffeine, alcohol or tobacco cause a return or increase in symptoms, you have a personal choice to make. Nicotine and the others are not the best way to treat a struggling brain.

Right. You mentioned flat affect also. What's your advice on combating depression/anxiety after a concussion? I've read about you and other people mentioning a healthy diet, but is that all? I've also read about something called CBD oil. Worth making a trip out to a legal state like Colorado/Seattle to use it?

Have you read the Vitamins sticky at the top ? It is a good start.

So barely hit my head again and now my emotions are everywhere...it seems like a cycle of anxiety and worry that makes it come back. Any direct one day fixes for this type of anxiety? I remember my first time having something like this, I decided to go to my neurologist. He said that anxiety is the cause and its self brought on, and with the reassurance I was actually good the next day.

How do I reassure myself, and how do you guys manage to do it. I understand vitamins and supplements but how do you not freak out everytime your head touches something? Silly but serious question

You need to teach yourself that touches, taps and even bumps and hits to your head are not injuries in most situations. CBT therapy could help. You will likely need somebody to help but as the saying goes, You need to be willing to change.

This could be a start. Sit with your eyes closed. Have someone touch your head with an object. Relax and breath through your response. Have them touch you with more force. Relax and breath through your response.

They could lightly slap the side of your head with a lightly rolled newspaper.

As I said earlier in this thread. You have caused your brain to memorize your anxiety response. You need to teach it to memorize a non-response.

Have a pillow fight. Have a water balloon fight. Neither will cause a concussion but can startle you and lead to anxiety.

What happened when your 'barely hit my head' ?

Great thanks for that. Retraining myself not to worry sounds good!

I was putting something into my car and my head lightly brushed the top part of the door frame in the car

You could work with your car. Touch various parts of your car with your head.

I encourage you to find someone who can help you. Your brain is far more tolerant of impacts that you would believe. The casual bumps are rarely even half what the experts say will even be a sub-concussive impact.
