If I have good self esteem, will I automatically have confidence?

My self esteem is sliding again, always (or never had it), burdened with worry and I'm not sure I ever had confidence on retrospect. I just faked it, I think, one day at a time. Could be cute, at times, but, really, in the long term, has not been terribly effective.

I don't need a new identity everytime I lack esteem, a coping mechanism I have adopted in the past in order to build confidence. I just need to remind myself of value or something. ( self) Any more ideas? Thanks
