You will not perish on account of thoughts with which you do not sympathize and from which you at least try to be freed. Only repent, & humble yourself. And God will forgive you.
When it is needful that a person be humbled, then not only the Superior, the sisters, strangers and near ones, but even all creation, according to the words of St. Isaac the Syrian, will rise up against that person.
Life is hard for you? Why, is there anyone for whom it is not hard? And do those in the world really have no troubles? Be patient, and a comforter will come in time. The Lord said, `In your patience possess ye your souls' (Lk. 21:19). If you are unable to do something and your health does not permit it, humble yourself and beg meekly [to be excused] - and above all, be patient. And if you lose patience in some situation, reproach yourself and ask God for help.
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
As for uprooting your passions, begin with self-reproach and with awareness of your own weaknesses; and consider yourself to be deserving of afflictions.
St. Peter of Damascus teaches, 'When joy comes, represent sorrow to yourself; and when you are encompassed by sorrow, try to awaken joy.' Thus you will be safeguarded both against deception and against despair.
