What you wrote reminds of these:
"Pain is inevitable, but suffering is optional." - Haruki Murakami "What doesn't kill you makes you stronger." - Friedrich Nietzsche "The greatest glory in living lies not in never falling, but in rising every time we fall." - Nelson Mandela
I was diagnosed with depression a few years ago, I barely had any friends at all, I just wanted to be gone. I learned empathy (very important, I only focused on myself or only used "others" to make point in an argument), I learned how to listen to others and respect their opinions, it changed me completely, I was able to love myself and, recently, love someone else.
Although I wouldn't consider SN or any other similar platform to create a blog, due to all of it being also archived, even if deleted by you, but also because sometimes we would be sharing very specific details of our life, I can't imagine the crumbs we're leaving behind.
Nevertheless, thank you for your post!
