Be patient with yourself as you learn the new ways of thinking. Treat yourself as you would someone you really loved. Self-hatred is only hating your own thoughts. Don't hate yourself for having the thoughts. Gently change your thoughts.
Criticism breaks down the inner spirit.
Praise builds it up. Praise yourself as much as you can. Tell yourself how well you are doing with every little thing. Find ways to support yourself. Reach out to friends and allow them to help you.
