Feeling Overwhelmed While Trying to Learn About Islam

I'm just so exhausted from trying to learn about Islam. It all started with praying, and then I had questions my mom couldn't answer. So I went online, and maybe that was a mistake-I ended up watching a lot of stuff, including content from ex-Muslims and refutations of them. I got confused and started doubting. I know I shouldn't, but I kept watching, and now it's hard to stop. I'm trying to read the Quran's translation and pray at least once a day, but it's all driven by fear. I'm scared of dying, of punishment, of Hell. My brother, who's now agnostic, told me to step back and focus on things that don't give me anxiety. But my hobbies-writing stories, drawing, listening to music, watching movies-make me feel guilty because some of them might be haram. I think writing stories is okay if they're clean, but I still feel bad. I've decided to take a break from Islamic content until next Friday, but I'm scared something might happen to me in the meantime. If I'm still alive by then, how do I start again without burning out? How do I learn about Islam slowly and focus on the mercy of Allah?
