Some of us find that when we quit drinking, we have other issues that need to be addressed. Sometimes we need the help of a professional - I had to get help with ongoing depression, OCD, and ADD. The worst thing we can do, of course, is to add alcohol to the mix.......
With things that provoke a lot of fear in us, it helps to take baby steps. You went outside today - so you took the first step. Feel good about that. Maybe tomorrow you can do it again and add something to it, like taking off the sunglasses. Make a goal (like "I won't run when I see a stranger") and work towards that.
You can keep a journal of your progress, too. Write down your feelings and any victories you have.
Remember that F.E.A.R. is "False Evidence Appearing Real." Recognize that just because you're afraid doesn't mean something bad will happen.
Prayers and hugs.......
