Keep trying. Try different things if you need to. Patch, gum, cold turkey, wellbutrin, chantrix...try them all if you need to (not all at once though...).
I tried the patch once and it didn't seem to do much for me. I tried cold turkey a couple of times. Sometimes I did okay for a week, sometimes longer. Ended up smoking again.
In the end, it may take multiple attempts using various methods to find one that works for you.
