You 100% will. My friend always tells me, "Our souls happen to have a body. We aren't bodies that happen to have a soul." Your baby had a soul that is now residing in Heaven. I like the verse in 2 Samuel 12:23 that says, "But now he is dead, wherefore should I fast? can I bring him back again? I shall go to him, but he shall not return to me." David had just lost his baby boy, and he also knew that he would see his baby again one day.
If writing a fictional story will help in your healing, do it! Healing looks different for everyone, and it is important to honor your own ways of healing. 🤍
