blackirish, Your Guardian Angel was appointed to you by God from the moment of your conception and your angel is always looking after you.
I pray the Chaplet of St. Michael every morning; I started this practice after learning that Mother Angelica and her Nuns also pray daily to St. Michael.
I see nothing wrong with you asking your Guardian Angel for help. Following is a prayer I say each morning to my Guardian Angel.
Consecration to the Holy Guardian Angel
You continually behold the face of our Father in heaven (Mt 18:10). God entrusted me to you from the very beginning of my life. I thank you with all my heart for your loving care. I commit myself to you and promise you my love and fidelity.
I beg you, protect me against my own weakness and against the attacks of the wicked spirits; enlighten my mind and my heart so that I may always know and accomplish the Will of God; and lead me to union with God the Father, the Son, and the Holy Spirit. Amen.:angel1:
Do not be afraid to ask for help. I will also remember you in my daily prayers.
