I have listed some of my favorite prayers below, maybe they will help you too in your time of need.

“God, be merciful to me, a sinner!” – Luke 18:13

The Miracle Prayer
Lord Jesus, I come before Thee, just as I am, I am sorry for my sins, I repent of my sins, please forgive me. In Thy Name, I forgive all others for what they have done against me. I renounce Satan, the evil spirits and all their works. I give Thee my entire self, Lord Jesus, I accept Thee as my Lord God and Savior. Heal me, change me, strengthen me in body, soul, and spirit.

Come Lord Jesus, cover me with Thy Precious Blood, and fill me with Thy Holy Spirit, I love Thee Lord Jesus, I praise Thee Lord Jesus, I thank Thee Jesus, I shall follow Thee every day of my life. Amen.

Mary, My Mother, Queen of Peace, all the Angels and Saints, please help me. Amen.

The Litany of Humility
O Jesus! meek and humble of heart, Hear me.
From the desire of being esteemed,
Deliver me, Jesus.

From the desire of being loved…
From the desire of being extolled …
From the desire of being honored …
From the desire of being praised …
From the desire of being preferred to others…
From the desire of being consulted …
From the desire of being approved …
From the fear of being humiliated …
From the fear of being despised…
From the fear of suffering rebukes …
From the fear of being calumniated …
From the fear of being forgotten …
From the fear of being ridiculed …
From the fear of being wronged …
From the fear of being suspected …

That others may be loved more than I,
Jesus, grant me the grace to desire it.

That others may be esteemed more than I …
That, in the opinion of the world,
others may increase and I may decrease …
That others may be chosen and I set aside …
That others may be praised and I unnoticed …
That others may be preferred to me in everything…
That others may become holier than I, provided that I may become as holy as I should…

Secretary of State for Pope Saint Pius X

Prayer of Abandonment
Father,
I abandon myself into Your hands;
do with me what You will.
Whatever You may do, I thank You;
I am ready for all, I accept all.
Let only Your will be done in me,
and in all Your creatures-
I wish no more than this, O Lord.
Into Your hands I commend my soul;
I offer it to You, Lord, and so need to give
myself, to surrender myself into Your hands without reserve,
and with boundless confidence,
for You are my Father.

Amen.

Prayer to St. Michael the Archangel
Saint Michael the Archangel,
defend us in battle.
Be our protection against the wickedness and snares of the devil.
May God rebuke him, we humbly pray;
and do Thou, O Prince of the Heavenly Host -
by the Divine Power of God -
cast into hell, satan and all the evil spirits,
who roam throughout the world seeking the ruin of souls.
Amen.

Prayer of St. Gertrude the Great
Eternal Father, I offer Thee the Most Precious Blood of Thy Divine Son, Jesus, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, for sinners in the universal church, those in my own home and within my family.  Amen.

St. Gertrude the Great is invoked for souls in purgatory and for living sinners. Our Lord told St. Gertrude that the following prayer would release 1000 souls from purgatory each time it is said. The prayer was extended to include living sinners as well.  More information about St. Gertrude the Great here.

Prayer to End Abortion
Lord God, I thank you today for the gift of my life,
And for the lives of all my brothers and sisters.

I know there is nothing that destroys more life than abortion,
Yet I rejoice that you have conquered death
by the Resurrection of Your Son.

I am ready to do my part in ending abortion.
Today I commit myself
Never to be silent,
Never to be passive,
Never to be forgetful of the unborn.

I commit myself to be active in the pro-life movement,
And never to stop defending life
Until all my brothers and sisters are protected,
And our nation once again becomes
A nation with liberty and justice
Not just for some, but for all.

Through Christ our Lord. Amen!

Prayer for Healing: Recreate Me
Heavenly Father, I call on you right now in a special way.
It is through your power that I was created.
Every breath I take,
every morning I wake,
and every moment of every hour,
I live under your power.
Father, I ask you now to touch me with that same power.
For if you created me from nothing,
you can certainly recreate me.
Fill me with the healing power of your spirit.
Cast out anything that should not be in me.
Mend what is broken.
Root out any unproductive cells.
Open any blocked arteries or veins and rebuild any damaged areas.
Remove all inflammation and cleanse any infection.
Let warmth of your healing love pass through my body
to make new any unhealthy areas
so that my body will function the way you created it to function.
And Father, restore me to full health
in mind and body so that I may serve you the rest of my life.
I ask this through Christ our Lord.
Amen.
