chakras are, among other things, clusters of neurons you have around all your major clusters of glands (responsible for producing, creating, repairing, energizing, your physical body)
Those neurons act as brains act. Think, project, remember, decide. 
So we think we think with the head brain but instead we are thinking mostly with our three lower brains. "Survive" "Run" "Fight"  "Reproduce (obtain pleasure)" "Eat/produce energy to: Survive run fight reproduce" 
That burns out anyone in a short time.
So telling these brains we are okay and doing okay and everything will be okay is letting them heal, repair, build, and release the expenditure of energy to the upper brains : Love, express, imagine, connect, receive.

For neurosis I would recommend mushrooms microdosing.  Psylocibes, amanita, reishi, lions mane. They would fix any nervous problem, nurture and create order. Cleanse parasites, reestablish gut microbiota, be seeds for happiness and meaningful life. You can stack them no problem and no side effects. All natural and regulatory adaptogenic medicine.

But it's key that you talk to your body. Nothing can work otherwise.
