I think it would be helpful to ask God and your Angel, “Please, my good brother Guardian Angel, tell me what's wrong I have done on this day.” When we earnestly pray to our Guardian Angel and ask him to remind us of our sins and faults, I believe he will recognize this and assist us as our Guardian Angel.
It is also possible to ask people whom you live with every day, “Please tell me what my errors are.” You can ask your husband or your wife, and you can even ask your adult children. You can also ask your colleagues at work, this may be helpful in some way.
Dear visitors of Gloria Dei and all who have already written or who will write a personal message to me. I am grateful for your attention, your kindness, for your spiritual support and especially for your sacrifices and prayers for me. God may reward you!
