Feeling distant from my faith and struggling with Islam

Assalamu alaikum everyone. I'm not sure if this is the right place to share, but I really need advice. About a month ago, I began having a hard time with hijab. I've worn it since I was 17 and now I'm almost 23, but lately I've started to dislike it. I couldn't understand why simply not covering my hair would lead to punishment. At first, I was just looking into whether the Quran actually commands covering hair or if it's about general modesty. While searching, I unfortunately came across content from atheists and agnostics on one side, and on the other, extremists who justify terrible things like murder and assault using the Quran and Hadith. Things went downhill from there. I began questioning the fairness of being punished for not covering my hair, then started doubting whether the Quran is truly divine or man-made, and now the worst part is I'm questioning everything I've been taught about Allah my whole life. It hurts so much, and I'm scared to admit that none of this makes sense anymore and just move on. I don't want to lose Allah or the love I had for Him, and I don't want to risk eternal punishment. But so much of the religion no longer feels merciful, kind, or even logical or real to me. How can I guide my heart back to accepting and loving it? I'm struggling really badly right now.
