Hi Juliana,
Congrats on tackling all your fears! Be sure to revel in that for just a moment.

As far as facing the escalator fear -- have you tried having someone you trust hold your hand while you are gently desensitizing yourself? Perhaps, if you didn't have to face it alone, it would be better for you.

I have to say, just hearing about others fears make facing mine a little easier, because I have to laugh at myself! Do you ever allow yourself to see the humor in some of what we put ourselves through? BTW, in my early twenties I was holed up with agoraphobia myself. No fun. Congrats again on all your accomplishments!
Take care,
Okie
