I would force yourself to continue to do what makes you afraid and take it head on--it's a mental game, there will be no harm to your child, so you need to tell you're fears that you are one BAMF and a force not to be reckoned with!

I'm sure that's not what you're looking for, but that's just my take on facing fears...make your fears afraid of you!

edit: Lately I've been scared of going fully under water, which was something I used to enjoy, but now I feel like someone is pushing me and holding me under. I haven't gone swimming since December, so when summer goes around I'm going to force myself to swim under water and make my fears go away.
