Brother Seeking Advice on Moving Forward After Renewing Faith - JazakAllah

Assalam Alaikum, I’m a young man studying in France, originally from an Arab country. Childhood wasn’t easy - my father was very strict though he cared, and my mother struggled with mental health when I was little. She was quite young when I was born and my father is much older than her. Growing up I often felt lonely and had some dark thoughts. I went through a really hard period and for about five years I cried a lot by myself, keeping it to myself. My maternal grandmother was a comfort to me but I only saw her a few times a year. Everyone knew my parents were serious, especially my mother. My grandmother used to try to talk to her and ask her to be gentler, but she couldn’t. Now with time I understand her anger and depression better. We never really spoke openly about these things with my parents, but it’s always been on my mind. In my youth I was often alone and struggled to make friends. Around 18–19 I started meeting new people and trusting some of them because I needed connection. Looking back, I made many mistakes then - getting involved in alcohol, parties, travel, and the like. I was trying to find happiness, move on, and enjoy life. But that didn’t fix the pain. I stayed depressed. Recently I’ve returned to my faith in Allah, and I’ve seen signs guiding me. I’ve spent months and years reflecting and processing everything, and I finally feel ready to change. I understand my parents more now and feel like we’re gradually reaching a better understanding. This feels like a new chapter, but I haven’t told anyone about it yet. I had plans with some friends, yet after thinking it over I realize our values don’t match, even if some of them mean well. I’m asking for advice - how should I move forward from here? What steps can I take to protect my faith, rebuild healthier relationships, and heal from the past? JazakAllah khair for any guidance.
