Here is a good talk by Fr. Adam Skwarczynski, a Polish priest. I recommend that you listen to his wise words on making a good confession (38:50 – 45:24). Going through the motion and hearing the priest absolve you at the end does not necessarily mean that God has forgiven you.
By the way, Fr. Adam says in this video that the Blessed Mother told him not only to ask God for much, but to ask God for everything. If you are praying for a few loved ones you know, God also wants you to pray for the billions whom you do not know. That is, never limit what you ask for!
