Angst and panic frequently originate in superficiality. At base, we live because we continue to breathe. We die when breath ceases.
So long as there is life . . . choose to LIVE. Enter each moment with fresh eyes. Accept that which is outside personal control. Simply let go of coveted strings used to puppet those in the life sphere. No one has rights to another's existence . . . only to privileges such as supporting, nurturing and/or loving them, for a space of time which must remain undeterminable.
When death visits, celebrate and value the living unfailingly while honoring and remembering those who have moved on. When new life begins, use every effort to sustain it.
Nothing else is, bottom line, very important at all.
