Mamabear is right. Insecurity comes with this package deal - bipolar whatever - and it passes. It´s good to keep that in mind. Sometimes I talk to my emotions and tell them: "Thanks, but you are just an emotion. You cannot take me to the guillotine."
It takes a little time to build up self-confidence, but faking it works up to a degree. You simulate behaviour patterns and it will be second nature. But I have strong feelings about the negative factor your mother is in your life. I tell you, we have similar ones! What kind of karma is this?
Sometimes I visualize her in a purple colour. We´re sitting at the same table and I´m also wrapped in purple. I tell her: "I bless you, I release you, I let you go."
