Dealing with Fear of the Inevitable

Asalaam-u-laikum everyone, I've struggled with intense anxiety about death since I was little, especially when I really dwell on the fact that it's the only certainty for all of us. I was raised Muslim, but in my teens, I drifted away and stopped praying for a while. Alhamdulillah, I'm back to practicing now-I started wearing the hijab a few months ago and felt closer to Allah, striving to improve. But lately, I feel disconnected again, and I'm not sure why. That's not my main worry though; what scares me is these doubts creeping in, making me wonder if any religion is real or just a way to handle the idea of nothingness after death. I know there's evidence supporting Islam, and that the Quran and Prophet Muhammad (SAW) foretold things we see today, yet sometimes it seems too perfect. I'm still learning more about my faith, working through the Quran in both English and Arabic, but I can't shake these fears. My chest tightens, I get dizzy, and I end up crying, terrified I'll never reunite with my loved ones. I get that I might be too attached to this dunya, but isn't that natural? My faith feels weak, and honestly, I'm scared-like, really scared. My throat closes up, and I freeze. Some nights, I stay awake fearing I'll die in my sleep, not because of hell, but because I worry there's just... nothing. The thought of death being unavoidable terrifies me. And if hell is real, I fear I might end up there anyway, feeling like I haven't been good enough. As a kid, I'd wake up crying to my mom, afraid to die, and now those feelings come back in short bursts. I calm down and try to avoid the topic, but it keeps popping up. I know it sounds contradictory-believing in Allah but fearing emptiness-but I'm lost on how to fix this or strengthen my iman. I don't want to be delusional, just to find some peace and acceptance. Any advice or insights would mean a lot.
