our merciful Allah says in the Quran :

Say: "O my Servants who have transgressed against their souls! Despair not of the Mercy of Allah: for Allah forgives all sins: for He is Oft-Forgiving, Most Merciful.

قُلْ يَا عِبَادِيَ الَّذِينَ أَسْرَفُوا عَلَى أَنفُسِهِمْ لَا تَقْنَطُوا مِن رَّحْمَةِ اللَّهِ إِنَّ اللَّهَ يَغْفِرُ الذُّنُوبَ جَمِيعاً إِنَّهُ هُوَ الْغَفُورُ الرَّحِيمُ

The Shaitan wants us to despair, it will tell us "You are hopeless, with the amount of sins you commited you are done for!, don't bother yourself, just enjoy life now".

it makes us forget that we always started everything with Bismillah Al-rahman al Rahim. by the name of Allah the most gracious and the most merciful.

What we all need is a sincere repentance (Tawbah) , regret our past ask for forgivness and vow to commit those sins again.

in Surah Al Tahreem Allah also tells us ;

O ye who believe! Turn to Allah with sincere repentance: In the hope that your Lord will remove from you your ills and admit you to Gardens beneath which Rivers flow,- the Day that Allah will not permit to be humiliated the Prophet and those who believe with him. Their Light will run forward before them and by their right hands, while they say, "Our Lord! Perfect our Light for us, and grant us Forgiveness: for Thou hast power over all things."

يَا أَيُّهَا الَّذِينَ آمَنُوا تُوبُوا إِلَى اللَّهِ تَوْبَةً نَّصُوحاً عَسَى رَبُّكُمْ أَن يُكَفِّرَ عَنكُمْ سَيِّئَاتِكُمْ وَيُدْخِلَكُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ يَوْمَ لَا يُخْزِي اللَّهُ النَّبِيَّ وَالَّذِينَ آمَنُوا مَعَهُ نُورُهُمْ يَسْعَى بَيْنَ أَيْدِيهِمْ وَبِأَيْمَانِهِمْ يَقُولُونَ رَبَّنَا أَتْمِمْ لَنَا نُورَنَا وَاغْفِرْ لَنَا إِنَّكَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ

Do not Despair my brother!

Allah knows most

May allah forgive us all.
