Are you angry, frustrated or annoyed with something...or someone? Do you feel you are a victim in someway or another? Are you overwhelmingly sad? Do you have fears, anxiety, very low self-image? Write about it. Write about your feelings and thoughts. Get it all out of you, and onto the paper. Put a date on it and keep it.
Keeping all your writings can help you down the road by going back and re-reading them. It can help you to see the progress you have made. Of course you can throw your writings away....but this is THERAPY....and it can help you a lot by keeping them.
