What can come in between you and repentance! If a person can repent from polytheism, then if you are honest in your repentance, and you fulfil all the conditions of repentance, and are sincere, then all those sins will be changed into good deeds, as Allaah says,
“وَٱلَّذِينَ لَا يَدْعُونَ مَعَ ٱللَّهِ إِلَـٰهًا ءَاخَرَ وَلَا يَقْتُلُونَ ٱلنَّفْسَ ٱلَّتِى حَرَّمَ ٱللَّهُ إِلَّا بِٱلْحَقِّ وَلَا يَزْنُونَ ۚ وَمَن يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًۭا. يُضَـٰعَفْ لَهُ ٱلْعَذَابُ يَوْمَ ٱلْقِيَـٰمَةِ وَيَخْلُدْ فِيهِۦ مُهَانًاإِلَّا مَن تَابَ وَءَامَنَ وَعَمِلَ عَمَلًۭا صَـٰلِحًۭا فَأُو۟لَـٰٓئِكَ يُبَدِّلُ ٱللَّهُ سَيِّـَٔاتِهِمْ حَسَنَـٰتٍۢ ۗ وَكَانَ ٱللَّهُ غَفُورًۭا رَّحِيمًۭا”
“˹They are those who do not invoke any other diety besides Allaah, nor take away human life, made sacred by Allaah, except with legal right, nor commit fornication; and whoever does any of this will face the Penalty. Their Punishment will be multiplied on the Day of Judgment, and they will remain in it forever, in disgrace. As for those who repent, believe, and do good deeds, they are the ones whose evil deeds Allaah will change into good deeds for Allaah is All-Forgiving, Most Merciful.” (Al-Furqaan 68-70)
This is if you are earnest in your repentance and it is accepted. Allaah’s help is sought.
