Congratulations on day 4 and facing your fears. Getting sober has allowed me to not only face my fears but go out and slay them. The trick is to start with the small fears and work your way up to the big ones.
When I got sober it was enough to face my fear of getting out of bed in the morning. Today I signed up for an acting class...not becUse I want to be an actor (he'll no!) but becUse public speaking terrifies me!
