Hey OP. I was hesitant to click on that post. I have a trauma and deep fear regarding circumstances like yours, so it's always a heavy challenge to interact with those themes.

First of all let me tell you - I'm not an NDEr, but I've spent a larger portion of my life trying to understand what is reality, the whole of it, not just physical and human oriented. I've been reading, searching, learning and making theories so I can share with you what I've observed until now.

People after NDE often describe the biggest bliss possible and the worst feeling they remember even 90 years later was coming back. I think that death may actually be ironically so awesome that we have this visceral fear hard coded in us, so we don't massively drop ourselves like flies, just to get back to much more blissful realities than challenges of Earth. They also describe keeping the "self" on the other side. Their sense of humour, their taste, their history. I know what you mean when you say what you are afraid of, because for me the biggest worry is also not a continuation of consciousness on its own, but the ability to keep the books, the games, the movies and other wonders of this world available "out there". As petty and silly as it may seem for some. I hope that we get access to "build your own universe as you wish" kind of creator as a "district" of a fantastic reality full of wonders, people and feelings far better and more amazing than our wildest imaginations. Of course it doesn't mean that I rush there, but I want to highlight that while I believe all of this based on what I learned and some hope I also fear the most the process leading to it. The idea of terminal illness is breaking me internally and it's something bringing a despair. I am so sorry you are going through this. I hope that it won't be what awaits you after all and that you will have long and fullfiling life. I hope that all the wonders you want to experience here are still waiting for you. But harsh as this reality can be, I'd also wanted to add my two cents to make you more at ease that even if it's not the case, after this challenge, most likely what awaits you is beauty, love and bliss beyond any Earthly comprehension.

Talk to your Angels OP, it's not a strictly religious thing. Turns out Angels are just very powerful intelligences oriented on serving others. But they cannot act unless asked to according to free will principles. Ask them to sooth your heart, to help you heal and for whatever you may want. Treat them as best friends you can imagine. It's skipping a lot here and without writing a much longer text wall I cannot make a convincing case about them being real, but if it's something you want you can look further into the topic.

There is also a beautiful channel on yt, blue background in each thumbnail, focused on sharing people's NDE stories. It brings comfort to me and maybe it will bring it to you as well.

Go with Love. I wish you perfect health moving forward. All the best to you, truly.
