finding old emails and photos from 10 years ago

I deep-dived into the numerous google drive accounts (I have around 40 now?? I take too many pictures) and also my main email from back in the day. I discovered childish emails sent to friends and teachers. I also discovered emails from the time my mum was sick. it is quite a unsettling contrast, seeing how I was telling this to my friend so nonchalantly. very different to how I describe it now.
