eli, I'm not sure how old you are, but if you're in your 20s or 30s I can tell you that as life goes on you will gain much more self-assurance.
Looking back, I can't believe some of the things I worried about when I was in my 20s and even later than that. I read somewhere on this forum that it's not menopause that affects a woman's mood but the fact that she's put up with enough sh**.
Not to say you won't benefit from some work with a therapist, or working on your fears. If you've been fair, apologised for mistakes and are at peace with you conscience, then really that's all you can do.
