Seeking Du'a for Guidance and Protection from Harmful Habits

As-salamu alaykum, I'm reaching out for your du'a and support. I've been struggling with alcoholism, and it's consumed my life. Alhamdu lillah, I've been guided to explore Islam, and I'm eager to leave my past behind. I'm frustrated with my previous experiences and feel that they didn't bring me any closer to Allah. I'm having trouble understanding the Islamic perspective on my previous beliefs and practices. Could someone please explain to me why certain beliefs are considered incorrect in Islam? I'm taking steps towards taking my shahada and starting a new path. Insha'Allah, I'll be able to fast for the first time this Ramadan and continue on a righteous path. Please make du'a for me to overcome my struggles and stay committed to my faith.
