It is absolutely amazing the power we have in our minds. Our minds can destroy us or heal us. I was amazed at how many of my anxieties and insecurities were eased when i stopped negatively reinforcing them. Instead of meeting new people and fearing them not liking me, i made sure to stay true to myself, be genuinely interested in them (which is not easy for me) and be kind and positive. It freaking worked! I wasn't anxious (much). I am working on bringing optimism into my life and being an agent of peace.
I'm so glad that you're using the power of your mind for healing! It's an absolutely amazing experience. Keep it up!
