I personally didn't go through that when I left religion because I never had a want to live forever or let my... mind(?) keep going without my body but I can see where others might. My best thing to suggest is think of it like a dreamless restful sleep. Do you worry about your friends and family while in a dreamless sleep? Do you have pain? Do you care if you will wake up? No you only have those pains/thoughts before and after the sleep. If you die you never know you are missing out, you don't know about pain or suffering, you are just... sleeping restfully. I find that very comforting.
