How can I tell what's right in Islam when everything seems so confusing?

Assalamu alaikum everyone. I know this might come across as overthinking-maybe it even is-and it might frustrate some people, but I truly need advice. Lately, I’ve been trying to take my deen more seriously. I’ve been watching lectures, reading hadiths, listening to debates, and learning about different rulings. But the more I dive in, the more overwhelmed I feel. Beard, music, drawing, praying at home, birthdays… the list keeps growing. I’m not rejecting all of these, and I’m trying to apply some of the rulings, but the issue is my family is moderately practicing-they stick to the basics-and now I don’t know how to act around them anymore. My biggest fear is Jahannam, and that’s what makes all of this feel so heavy. Almost everything in daily life makes me question if I’m doing something wrong. For example, my family watches TV and dramas where sometimes there are women not dressed properly or there’s music playing. Is that haram? I know intentions matter, right? But I’ve heard different rulings. When we go to malls or restaurants, music is everywhere; you can’t escape it. Some say only certain genres are problematic, while others point to hadiths suggesting instruments themselves are haram. I barely listen to music, maybe 10–20 minutes sometimes to focus on work, but then I wonder if I’m still sinning. I even thought about learning piano this summer, but I decided against it. Even educational reels have music-am I supposed to avoid those too? If I watch something with music in it, am I supporting haram just by viewing it? I don’t know what to follow anymore. Can I just take the interpretation that feels right to me, or is that just making excuses? My beard barely grows-maybe genetics, because even my father doesn’t have one, or at least that’s what I think; I haven’t really let it grow long enough. I shave because the tiny hairs that do appear look darker against my skin tone. Am I sinning for that? Insha’Allah, I plan to try growing it later with some serums and such. My sister wears hijab off and on-should I say something to her? If I do, my family will act like I’ve become an extremist overnight. Same with birthdays: we don’t do big parties, just cake and gifts, nothing extreme, but I see people saying even saying “happy birthday” isn’t allowed. So what’s actually correct? Someone please tell me how to know if we’re sinning or not. I also think about things like my mother posting family travel photos where she wasn’t wearing hijab, and I worry if she’s earning sin. And the books I enjoy are mostly fiction, but many include romance. Some scholars say to avoid it, others say it’s okay to a degree if it’s not explicit. Which do I follow? Then there’s shaking hands with non-mahram women. If I’m on stage getting an award or my mom’s friend extends her hand, what do I do? Some scholars say never shake, just gesture respectfully. Others say there are exceptions. If I refuse, it might make Islam look bad to people, and my family would be upset. And scholars also debate games that involve luck, like ludo, chess, or cards. So many opinions-but which is right? I could list more, but you get the idea. Every single issue comes with five different opinions. How am I supposed to know which one is correct? Is it okay to just go with whichever opinion feels strongest, or am I just picking what’s easier for me? And if I pick the wrong one, am I held accountable? Sometimes I wish there was a halal-or-haram detector for daily stuff because I don’t know what I’m doing anymore. Am I making this harder on myself than it needs to be, or is it really this difficult? Does the Quran address these things? Is it wrong to question some hadiths? I’m scared of following a wrong interpretation. I just want someone to tell me how to actually find the right path. How do I live my life? JazakAllah khair for any guidance.
