The writing is a fab idea if it works for you. I want to be a superhero whose power is writing fabulous stories in seconds that everyone loves.
I write my feelings down in various forms all the time. It can also help when you read over it in future. I recently found some of my old notebooks from 3 or 4 years ago and I didn't realise just how depressed I was. If I feel down now, I look back over them and consider myself lucky for getting through that unscathed.
Sometimes I also choose a song I like and write funny lyrics to the music. I know it can be hard to find things funny when you're depressed but I highly recommend it.
You could also chuck on a comedy DVD. I usually go for Lee Evans stand up.
Laughter really is the best medicine, if you can find it.
I really hope you do. Big hugs
If that's not too weird
