You can't live and PRACTICE the Catholic Faith without Mass and the Sacraments. Not unless God means for you to.
Just like with martyrdom. You should never seek it on your own. It must be God's idea. That is because torture is too much for most people to endure without breaking -- especially the weak. But when it's God's will, He (and he alone) provides the strength. (as seen by the large number of women and children martyrs) But if you ever find yourself under "Catholic persecution" torture, as soon as you stop praying, you will snap under the torture and probably lose your soul. It's that simple.
