Healing from any trauma does not happen in a day. How many days does it take? What does it mean to you? What do you want the quality of your life to be like? Persistent injuries took a long time to develop and they will take an equally long time to improve. Loving and caring for oneself is very hard to do when you are used to caring for others or working a job that you have done forever and that is now increasingly harder for you to preform. Times change and so must we. That does not mean that you must neglect your body for the sake of others.
What is it that the steward/stewardess tells us for our inflight instruction? "In the event of loss of cabin pressure, a mask will be released from above your seat. Please put your own mask on first before assisting others." how long will it take to "put our own mask on", before we can help others? However long it takes to get the job done.....YOU need healing and relief before YOU can help others or even do you job.
Consistency, consistency, consistency. Being as persistent as your injury is a start.
