Do not be afraid to come back home to your Faith. That connection that you need and that you desire that alone completes you can only be found in Christ... "Abide in Me and I in you. As a branch cannot bear fruit of itself, unless it abides in the vine, so neither can you, unless you abide in Me" (Jn 15:4). He waits for you to come back.
There was a long time where I had turned away from Him and the Church & Sacramental life. My life had really turned more than sour... actually more like dark vomit and I didn't realize what was missing in my life until I had a serious car accident after drinking and driving. I realized where my life was going without Him and it literally scared the HELL out of me because He revealed to me that this is where I was headed if I continued to run away from Him. I cried out that if I loved Him why would I be going to Hell. He let me know that I was choosing Hell by not letting Him deeply into my life. He told me that if He dwells in Heaven and I choose not to let Him in... what am I left with? There is only one other option if we aren't aiming for Heaven with God in our life. Christ reaches out to you with His Wounds to heal you and to forgive you but you have to WANT this. He won't force you to Heaven and won't pry open the door of you life with a crowbar. He waits for you to invite Him in and to come back to His Church. All it takes is for you to go to Confession and be absolved from your sins. One simple step... and it is nothing in comparison to what it cost Our Lord to make this available to you. There is an OCEAN of His Mercy waiting to be poured upon you... you just have to dive in.
