Recalling the Sea and Collecting Treasures

How to start? Ah... What do I start with? Oh... Yes, I want to start recording my life Hypothyroidism + cerebrospinal fluid drip leads to worse and worse memory and greater forgetfulness. I am really worried that one day I will have Alzheimer's disease, a deafening dementia that is silent than the sea. I have to record my current life experiences, thoughts, joys, sorrows and sorrows. When I really become dementia, my family can read my opinions when I am awake, so that they will not feel guilty when taking measures against me.
