Addiction and Converson

For quiet some time I have concluded that my greatest enemy is myself. I have put so much criteria on people and their ideas but until now I have for quiet some time have never even been fruitful. I am still haunted by the same bodily and passionate addictions in the past that I have sworn to eliminate. It is harder that it really is, this controlling of the self and mastering ones psyche...
I really think I cannot do this alone, I have to seek help... Can I pray now? I am missing the rosary, it has kept me from sinning until I stopped it, I miss attending the mass too.
My God, do I still have a chance of turning back to you?
