Anxiety is basically the worst of my PCS symptoms, and my best recommendation for the worries about school/work is to take it slow. Depending on your symptoms and how you are able to deal with them, I might even suggest seeing if you can take a break from work for a few weeks. I made the mistake of jumping right back into my daily life after I sustained a concussion, and I feel like I'm paying for it 3.5 months later. Rest is truly an important part of recovery.
As for the neurologist, I think it depends on who you see & what their knowledge is in regards to concussions. When I saw a neurologist, they were of little help, and I rely much more heavily on my PCP to treat each symptom of PCS. You're very early on in your recovery, so you may not even need to worry about persisting symptoms, most people I know have recovered from concussions quite quickly. There are things like vestibular therapy, vision therapy, etc.
Good luck!
