Hi CA!!! I do hope that this will pass soon. I have known a couple of agoraphobics in my day and have perhaps a small understanding of how you feel. Perhaps think about the fact that you left your house to go get liquor, you would just be leaving your house to perhaps take a short walk around the block......no personal interactions necessary.
But just know that Rome wasn't built in a day...one small step, one small victory at a time!
Hugs, HG
