Feeling Overwhelmed by the Thought of Eternity

Assalamu alaikum, everyone. Has anyone else ever questioned the concept of existing forever, whether in Jannah or otherwise? Sometimes, I feel like I’m not truly cut out for eternal life-like maybe it would’ve been simpler if I hadn’t been created at all, since Allah could have easily chosen another soul without changing a thing. From my perspective, everything just seems to lose its meaning when you think about it all dissolving after death. Even the idea of unimaginable joy in heaven feels... hollow, you know? It’s like, why create me knowing I’d wrestle with these thoughts? It’s not about denying Allah’s wisdom, but honestly, sometimes it just feels like a heavy test. I know it might sound strange, but I’ve even wished to be something without an eternal soul, just so there’d be an end. And please, I’m not looking for advice to ‘fix’ my mind or be ‘healed’-I don’t want to lose who I am through forced change. Does having these doubts make me less of a believer? I do believe in Allah, but that doesn’t mean I feel ready to witness Him forever. Anyway, I hope this doesn’t upset anyone, and may Allah grant us all ease and guidance. Jazakum Allahu khairan for reading.
