Hun, yes a therapist or hypnotist can help you out with emotional problems and such, but being brave is up to you. I'm scared just to have people look at me weird. But I've been forcing myself little by little to be more active in public. Just take baby steps. Think of something small that you're embarrassed or scared of doing in public, and just do it. Once you take the first step, it so much easier to go further. I went from pretty much only singing when I was bored at work to being bubbly, loud, wearing scented lotions, swaying my hips when I walk, and dancing a little when I feel like singing in just a couple days. But people have noticed that I seem happier, and that makes me happy. It only takes a couple acts of bravery to get over years of fears. And it sounds like wife would be more than willing to help you out in doing this.
There's nothing wrong with just wanting to be yourself. *hugs*
