I have so many underlying emotions that I can really not account for. But, when I start compiling my weekly mail to my T, I find I battle to stop. It's almost like it's not me writing. I manage to scrape some really emotional and deep issues; things I never realised were there. It's scary, but easier once I've pressed the 'send' button and know I've shared, and that some of these issues will be addressed in the next session.
I find that as I start writing, the answers come to me, and patterns do emerge. It's like a puzzle where the pieces all start coming together.

Just try writing about what you're feeling now, and you'll marvel at where you find your pen taking you!

Off-hand I could not answer the question about self-hate; and it's something I also battle with somewhat.
