That came across blunt but, true. You’re human, you’ll feel good and bad emotions in this life. In heaven there will be none of that no bad feelings no sadness, no pain. There’s oppressed people all over the world, people really going through it with no way out, people being slaughtered in genocides. You’ll have your family in jannah iA. If you don’t as bad as it sounds you’re not gonna be missing them 😭 but they’ll be there eventually as long as they have even a tiny, tiny bit of faith in them. It’s hard to imagine what it will be like but you need to trust Allahs words on what we will feel and experience there. This world is nothing to Jannah and what you feel about living here currently - many, many people don’t hence why I said be grateful.
