Sara,
I think it is like a lot of things, you have to take it one day at a time. I suffer from depression and had to take some time off work a few years ago, I started having panic attacks in the car.
I stayed home for over a month and would not go anywhere in the car.
I finally started out by driving down the road and back home, then to Wal Mart and so on.
I think you are taking it slow and you should be proud that you made it 2 days in a row.
Always remember, your BYC friends are here as well to help you. This world is in rough shape right now and no matter what you believe having faith that you can make it through is important.
Hang in there!
