What is the after life like?

Please someone tell me, my best friend just passed away recently and it’s making me crazy not knowing where she is and how she was just here in the physical and now she’s not. It’s making me question this all. Can someone please tell me about a NDE if you’ve had one ? I would love to know because this is honestly scaring me and all I want to do is see her and know what’s she’s doing. I want to know what the spirit realm is like and what everyone is doing there who crossed over. I cry everyday missing her I just want to see her again. Someone please explain if you know it would help a little and comfort me some.
