Even though you say no matter, that I am still a Catholic, non-practicing one at that and can go to confession and be restored to the faith, I feel nothing.
Blueblades, as Tom mentioned, when you were baptized, you were marked with an indelible mark. God adopted you. He never un-adopts you. One of the requirements for faith is that you have to want it. Faith is a gift. If you want to find out about God and whether or not he's real or exists or there is anything worth believing in for you, take a moment and ASK God for the faith to find the answers you seek. It may seem silly but what can it hurt?
Catholics believe that each of us has a guardian angel with us at all times. It's the guardian angel's job, in part, to help lead you to God, if you so desire it. If you ask God and your guardian angel for assistance, you will receive it. You won't get hit by a bolt of lightning, but you will find the guidance you seek.
