Every night before I go to bed I write down 10 things I am grateful/thankful/happy for. It can be something simple that makes me laugh because its a little pathetic, like the fact that after 24 years I have finally stopped biting my nails and grown them long, so I can now buy a really awesome nail file and look cool, or something that made me smile during the day, or something bigger like being happy I am no longer being abused or bullied, or that I now have a real bed to sleep on instead of boards. It may take some time but it makes you begin to notice the good things a little more, even just simple things, instead of running on negative 24/7. I do consider myself a very negative person but surrounding myself with more positive things makes me feel better. Just the other day I bought a little yellow polka dot tea cup and saucer to drink tea. And I dry lavender and put it in my room because I like the way it looks. And I listen to classical music. Just surround yourself with little beautiful things.
