Welcome to NeuroTalk. Sorry to hear of your accident and injury.
My first impression is that you wrongly think your only injury was the concussion. Any concussion also includes a stress or outright injury to the neck. Unless neck injuries get treated, often the concussion symptoms will persist at a magnified intensity.
Chiro can be helpful but the many different techniques can make finding good treatment difficult. Also, some physical therapists/physiotherapists can help with neck traction and manipulation and some can help with myofacial release treatments.
Until you find help with these therapies, you should start some self therapy with icing your upper neck and any area with tenderness.
It is very unlikely that you are causing more damage to you brain. You are delaying you recovery. As mentioned by rmschaver, you need quiet rest. This means minimal cognitive and physical activity. Running a hotel sounds rough unless you can stay in the back office and minimize guest contact. Phone contact with a head set may be acceptable.
You need to try to forget about your normal activities unless you can set your own time schedule. Trying to keep up with a preset schedule is too stressful. When you need to do a task like feeding animals, try to go slow and act with purpose. This is a skill you should master. Sometimes, we call it "Stop to Think" or "Stop to Act." Trying to go on like you used to with the same momentum as before will be problematic.
In time, you can return to your prior level of activities. But, you likely need to plan on a month or two of quiet rest with very moderated activities.
The 'vitamin supplement' thread will give you some ideas of how to provide good nutrition to your brain. The injured brain needs additional nutrition to help it flush the injury toxins before it can start to heal.
Please feel free to post any struggles you are having.
My best to you.

60 years old, retired due to disability, married 34 years, father of three, grandfather of four, Suffered a serious concussion at 10 years old (1965) stopped most driving after concussion at 46 years old (2001), Post Concussion Syndrome/Multiple Concussion/Impact Syndrome with PTSD, immediate/short term visual and auditory memory problems, slowed processing speed, visual/auditory processing difficulties, insomnia, absence seizures, OCD, 14 concussions since first concussion at 8 years old, Taking paroxetine for 14 years and gabapentin for 12 years. Added L-Tryptophan and stopped paroxetine after 3 months of tapering. I currently take 100 mgs of 5-HTP AM, 500 mgs of L-Tryptophan at noon.
As of Nov 15th, Due to high stress issues resulting in PTSD, docs put me on 3 meds. Clonazepam but only for 30 days ) .125 mgs twice daily (Doc presc. .25 mgs 2x daily but half a tablet is good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic that usually causes weight gain before bed. I lost over 30 pounds since mid July. It just stopped the weight loss. Took me off the gabapentin.
May 2014, I am off the olanzapine due to a 6 fold price increase. Back on 600 mgs of gabapentin before bed.
Oct 2014, off the Celexa. The 5-HTP is doing much better and leaves me feeling normal as compared to being on an SSRI.
I am also taking L-Theanine to help with GABA regulation
