Here is an exercise that I use in writing classes. It's a great daily practice and works especially well when I feel self-pity or that other people are responsible for my pain. It's called "Don't Be a Victim" and the exercise goes like this:
Complete each sentence in your notebook with your first thought.
I HAVE TO_____________________________
After you have done that then:
Then go back and cross out “Have” and replace it with “Choose”
Then go back and cross out “Can’t” and replace it with “Don’t want to ”.
Read them again.
Teach yourself not to be a victim:
If you don’t like your life fix it.
Don’t feel sorry for yourself; it will destroy you.
Accept responsibility for your own life.
Stop lying to yourself.
