St. Bernard goes so far as to say that it is almost useless to pray for habitual sinners,—that we must weep over them as lost forever. If they no longer see their danger, how can they escape the precipice? To preserve them from it, a miracle of grace is necessary. The miserable wretches will open their eyes in hell, when the sight of their misery will serve only to make them weep more bitterly over their folly.
Habits are very serious
this is what you are doing

What does the sinner do when he commits mortal sin? He insults God, he dishonors him, he afflicts him. In the first place, mortal sin is an insult offered to God. The malice of an insult is, as St. Thomas says; estimated from the condition of the person who receives, and of the person who offers, the insult. It is sinful to offend a peasant; it is more criminal to insult a nobleman; but to treat a monarch with contempt and insolence, is a still greater crime. Who is God? He is Lord of lords, and King of kings.1 He is a being of infinite majesty, before whom all the princes of the earth and all the saints and angels are less than an atom of sand. As a drop of a bucket. . . as a little dust.2 The Prophet Osee adds, that compared with the greatness of God, all creatures are as insignificant as if they did not exist. All nations, he says, are before Him as if they had no being at all.3 Such is God; and what is man? He is, according to St. Bernard, a heap of worms, the food of worms, by which he shall be soon devoured. He is miserable, and poor, and blind, and naked.4 Man is a miserable worm, that can do nothing: he is so blind that he knows nothing, and so poor and naked that he possesses nothing. And this miserable worm voluntarily insults a God! “Vile dust,” says the same St. Bernard, “dares to provoke such tremendous majesty.”5 The angelic Doctor, then, had just reason to say that the sin of man contains, as it were, an infinite malice. And St. Augustine calls sin “an infinite evil.”6 Hence, were all men and angels to offer themselves to death and annihilation, such an offering would not satisfy for a single sin. God punishes sin with the pains of hell; but all theologians teach that this chastisement is less than sin deserves
Christ also gave us the means to overcome this stuff in the sacrements, if you ignore those and reject confession that's your choice and you can't expect to overcome them on your own. Don't expect Christ to help you if you aren't already using what he's given us.
