Keeping a diary

I have kept a diary for 8 years and i am now 16. I write in it my feelings, what i have done, my fears or anything random that comes into my head when writing. Often when I have an urge to write in my diary  i don't know what to write. But once I start writing all these thoughts just come flowing out and i end up writing quite a bit. I find it relaxing. When im in Nigeria i often like to write in my diary whilst sitting in a tree though i don't know why. I still remember when i got my first diary. I didn't want to be parted from it and kept writing in it the whole day.
