Writing is very therapeutic – especially if you don’t share it with anyone. When you write just for yourself, to organize your thoughts, excise your pain, record your memories, or for any reason you like, it’s like a cleanse for your spirit.
I recommend you buy a journal even if you only write in it once in your entire life. That one entry is the entry that may make the difference between feeling better and moving on or holding onto something for way too long.
And when you write for yourself it doesn’t matter if you know how to spell or any of the grammar rules. No readers (you don’t have to read what you write. just get it down) equal no judgment.
