Congrats on choosing to detox and on your week sober! I love journaling/writing also. And like you, I attempted to at times when I was still drinking heavily and have found similar scribblings. If you’re interested, here’s a post about finding one of mine:
Journal post
May I recommend you write something below that sentence in response as your new sober self and then start fresh on the next page? I just can see how that would be such a powerful entry and reminder of what you’re leaving behind and what you’re working on now.
Whatever you choose, happy writing!
