Daily Journaling?

My yoga teacher recommended to write a diary. I used to write diaries all throughout my teens. On and off. Nowadays I stop whenever I feel overwhelmed and unwell. Which I do feel quite often.

I understand her point of reflecting daily and someday looking back. But I personally really hate writing down when bad things happen because I want to forget them. I get triggered really easily. Whenever I read my diaries from school I feel like I'm 14 again, being bullied and having peak social anxiety. 

At the same time I feel like us humans we forget daily things very easily with time. Even good things. And I want to remember them. I want to cherish the mundane more.

So will I be journaling daily again? I don't know. We'll see.
