If you are feeling guilty about something before it even happens, thats the Holy Spirit talking to you. Do not be like this guy! Pray first and God will give you the courage to stand firm in trials, temptations and tough times.
If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. – Hebrews 10:26-27
