ASSALAMU ALAIKUM - Seeking Guidance Before Rehab and a Possible Embrace of Islam

ASSALAMU ALAIKUM. I'm asking for dua and advice from the children of Allah. I've been dealing with depression and addiction for years. For five years I've struggled with alcoholism. In 2024 I joined a Christian church hoping to heal spiritually and serve Christ, but I still felt overwhelmed by forces that crushed my will to get better. My mother became ill and I spent about three months in the hospital caring for her. During that time I drank and smoked secretly in the hospital to try to forget and escape. The only relief was sleep - that wanting to not exist for a few hours is really dangerous. My mother passed away eleven months ago, and since then I've been drinking every day, feeling ill and ending up in hospital. On July 23rd I had a heart attack. After that I managed to stay sober for a month, but then I fell back into it. Today I'm sober so I can speak clearly with you. A few months ago Islam entered my life. At first it was curiosity, then a real interest in its teachings of love, discipline, and turning to Allah. I was struck by how Islam encourages leaving addictions and reducing attachment to worldly things. I still have a lot to learn, but listening to nasheeds and learning basic teachings has calmed my heart and eased my anxiety. My name is Lucas and I'm Brazilian. I grew up Catholic and had contact with African-based religions in my family. As a teen I visited a spiritualist center, and as an adult I joined a Christian church where I truly felt close to God. But when I was weak, evil seemed to take advantage and bring problems, frustrations, and despair, and I lost my faith and stopped praying. Brazil is a very mixed, mostly secular country; Islam is rare where I live. In my city there's only one mosque while churches are everywhere. Many people hold negative stereotypes about Arabs and Muslims because of media influence. To summarize: tomorrow I will voluntarily enter a rehab clinic, following family advice. There will be support and a Christian church on site. I want your honest opinion. I have no problem respecting all faiths and I try to honor everyone’s beliefs - faith is personal and Allah is One. But I'm afraid to tell my family and friends about Islam and my wish to visit a mosque. I'm also worried about how people will view me in public. Living in a non-Muslim country is hard and requires patience and steadfastness. I often think about saying the Shahada and embracing Islam, but the mosque is far away and my stay in the clinic may be long and without internet. It could be a time for real reflection and talking to myself and to Allah. I would be grateful for your duas, advice, and experiences from anyone who has converted or struggled with addiction while exploring Islam. Jazakum Allahu khairan.
