Learning Self-love

I have your two set DVD’s, The Happiness Prescription. I just love them. I use the mantras and when I am all by myself I believe that I love myself. As soon as I am with others I feel the doubt I still allow myself to see me through my projection of what others think and say. Any suggestions on how I might get were I want to be.
I truly believe that if I learn to accept and love myself then I will do the same with others and be better able to accept love in my life.
Thanks for your attention to this matter.s
