Let me share an analogy that helped me. I refer to it as the airplane analogy.
When we fly on a commercial flight, there is a pre-flight safety speech.
The flight attendant goes through the safety steps in case of an emergency.
They teach us that there are air masks that drop from the overhead in the event of a loss of cabin pressure.
They instruct us to put on our own mask before we attempt to assist others.
Yes, that is what we are encouraging you to do.
Put on your own life saving oxygen mask, before you attempt to help another.
As a parent, that is difficult. I know that I gave up a part of my life to be sure that my children's needs were met. Looking back, I don't think I always gave in a healthy way. I gave until I was lost in the giving process. I am learning that there needs to be time for me also. I can't be helpful to others until I have taken care of myself.
