Writing definitely is good therapy. Because if we let the thoughts stay in our head, or fight them, they become stronger and can even become a nuisance.

Like you say we can't take life too seriously. I think that is definitely key. I've had quite a lot of problems in my life with negative thoughts and depression, the best medicine for me has always been to realize that I have to be my own best friend. Sounds cheesy but I think it's true.

Sometimes we push ourselves too hard and sometimes not enough. Like you say somewhere in between is the holy
Grail !
