Hi Ruby
I've had my own Mental Health issues as the majorty of you are aware. You don't get to 43 stone without them.
Back in the days when I was just "a bit" overweight. - I turned myself into class joker in order to impress the ladies.
The when I became "a bit" fat - I turned myself into the typical big jolly fat man.
Then when I became "very" fat I also became very depressed, which turned into a big cycle of self lothing, eating to comfort myself etc - as I could do very little else, I decided to start writing in order to express myself. It was great, because behind a script or piece of writing you can be whoever you want to be and aren't judged by first impressions.
In short trying to be funny was one of my ways of compenstating for my physical "weakness" which were the result of my mental health problems.
