Trying to Wrap My Head Around Jannah

As-salamu alaykum everyone, I've been pondering this for a while and wanted to share my thoughts, hoping to get some advice or other viewpoints. I'm a Muslim, and I truly believe in Allah, the Quran, and the essentials of Islam. My issue isn't with faith per se; it's more with wrapping my head around the concept of Jannah. Somehow, the notion of eternal paradise feels... tricky for me to really accept or feel connected to. The idea of having no worries, no sadness, and just endless joy sounds perfect, but it also seems kind of hard to picture. I struggle to understand what it means to live without all the emotions we have now-both good and bad-that shape who we are. Part of me wonders, if I'm not experiencing life like I do now, am I still myself? That's where I feel stuck. Because of this, I sometimes catch myself thinking maybe "heaven" and "hell" are things we go through in this life rather than after. Like, living right, being kind, and doing good brings you inner calm (sort of a "heaven"), while being mean or dishonest leads to feeling empty or unhappy (sort of a "hell"). And maybe when we die, it's just... over. But at the same time, I know the Quran talks a lot about the afterlife, Jannah, and Jahannam, and it's described so clearly and seriously, especially about Hell. So I feel really torn. I'm not saying I don't believe; I just have a hard time really feeling this part of it. So here's my question for you all: How do you make sense of Jannah in a way that feels meaningful and real to you? Did any particular explanation or perspective help you work through this?
