Are you worried that you will run into someone, him, her, or a friend that doesn't know? I ask because my driving wasn't the problem. It was because I had broke down before in a place I didn't know, and it took hours to get help. My panic in crowds wasn't because of the people, but because my parents lost me at Disney when I was seven. It took me a while to figure out what the real reasons for the attacks were. Knowing help to beat them.( I still get regular panic attacks here and there but they are when I am really under a lot of pressure.)
I would try driving to the store and sit in the parking lot. If you feel okay then go in the store and walk around or grab one item and then leave.
Try talking to yourself(I did this). Say ...Hopeful, you are ok. It is just a store. Verbally reasuring yourself.
I know it sounds silly but it did work for me.
What doesn't kill me, scars me.
I think the idea if small baby steps is great. Good luck. I wish you the best in conquering this.
