swift,

You are definitely stressed out. Anxiety is the most severe stage of stress. Being 'so scared' is the extreme point of anxiety.

You should be taking time off for quiet rest. There is no way to recover without quiet rest. No drinking, no partying, no exercise, and minimal work.

You sound like a Type A personality. You need to be in control. This is counter to recovery from a concussion. You need to find a way to relax and let your mind let go. I would not be surprised you use alcohol to achieve this state in the past. No more alcohol.

You should find a doctor with experience with concussions to direct you to help. You need this help. ER's are not much help except to rule out life threatening issues. An Urgent Care clinic may help.

Let us know more about your symptoms. There is good help here.

My best to you.
