Myrna,
My sincere prayers are with you in this difficult time. God in His Justice and Mercy will give you the grace to persevere in these agonizing moments. It sounds like you have already made sure your dear mother doesn't die an unprepared or unprovided death since she's wearing her scapular and had already access to the last sacrament. Let's pray to St. Joseph in these moments:
Prayer to St. Joseph for the Dying
PRAYER FOR THE AGONIZING
O St. JOSEPH, protector of those in agony, take pity on those
who at this very moment when I pray to thee are engaged in
their last combat.
O blessed Joseph, take pity on my soul too when the hour of
the final battle shall arrive for me. Then, O my holy patron, do
not abandon me, but grant me thine assistance; show that thou
art my good father, and obtain that my Divine Savior may receive
me with mercy into that abode where the elect enjoy a life
that shall never end. Amen.
PRAYER FOR THE SOULS IN THE AGONY OF DEATH
ETERNAL Father, by the love Thou bearest toward St. Joseph,
who was chosen by Thee from among all men to exercise Thy
divine fatherhood over the Thy Son made Man, have mercy on
us and upon all poor souls who are in their agony.
Our Father . . . Hail Mary . . . Glory Be . . .
ETERNAL Son of God, by the love Thou bearest toward
St. Joseph, who was Thy most faithful guardian upon earth,
have mercy on us and upon all poor souls who are in their agony.
Our Father . . . Hail Mary . . . Glory Be . . .
ETERNAL Spirit of God, by the love Thou bearest toward
St. Joseph, who guarded with such tender care most holy Mary,
Thy beloved spouse, have mercy on us and upon all poor souls who are in their agony.
