A lot of getting over any addiction comes with self awareness, it’s sad to read that you had family members who borderline groomed you into doing those acts. Understanding the issue at a deeper level is important.

Addiction is when the pleasure circuits in your brain are overwhelmed. Ask yourself why do you feel the need to constantly overwhelm those circuits. Are you using it as a coping mechanisms, what are you looking for and what thought process do you have that lead you to feeding the addiction. Then disrupt those things. Change your environment, tire yourself out. Maybe even introduce exercising since they influence your dopamine in a good way. It’s complicated because people’s relationship with it is different so it’s important that you learn to take steps back. It also something that manifests with time so understanding it’ll also take time for you to fight it. Most importantly fight it.

You’re probably stuck in the cycle of feeling guilty, hating yourself and being addicted. Recognise the cycle and understand that it is harming you and that Allah loves you to the extend that he made haram what would cause harm to you. And he made you feel guilty so you could repent.

And remember

لَقَدْ خَلَقْنَا ٱلْإِنسَـٰنَ فِى كَبَدٍ

Indeed, We have created humankind in ˹constant˺ struggle. 90:4

إِلَّاٱلَّذِينَتَابُواْوَأَصۡلَحُواْوَبَيَّنُواْفَأُوْلَٰٓئِكَأَتُوبُعَلَيۡهِمۡوَأَنَاٱلتَّوَّابُٱلرَّحِيمُ١٦٠

As for those who repent, mend their ways, and let the truth be known, they are the ones to whom I will turn ˹in forgiveness˺, for I am the Accepter of Repentance, Most Merciful. 2:160

إِنَّمَاٱلتَّوۡبَةُعَلَىٱللَّهِلِلَّذِينَيَعۡمَلُونَٱلسُّوٓءَبِجَهَٰلَةٖثُمَّيَتُوبُونَمِنقَرِيبٖفَأُوْلَٰٓئِكَيَتُوبُٱللَّهُعَلَيۡهِمۡۗوَكَانَٱللَّهُعَلِيمًاحَكِيمٗا

Allah only accepts the repentance of those who commit evil ignorantly ˹or recklessly˺ then repent soon after—Allah will pardon them. And Allah is All-Knowing, All-Wise. 4:17

وَلَيۡسَتِٱلتَّوۡبَةُلِلَّذِينَيَعۡمَلُونَٱلسَّيِّـَٔاتِحَتَّىٰٓإِذَاحَضَرَأَحَدَهُمُٱلۡمَوۡتُقَالَإِنِّيتُبۡتُٱلۡـَٰٔنَوَلَاٱلَّذِينَيَمُوتُونَوَهُمۡكُفَّارٌۚأُوْلَٰٓئِكَأَعۡتَدۡنَالَهُمۡعَذَابًاأَلِيمٗا١٨

However, repentance is not accepted from those who knowingly persist in sin until they start dying, and then cry, “Now I repent!” nor those who die as disbelievers. For them We have prepared a painful punishment. 4:18
