Hi Rohit,
I've had a couple of stages like this, and felt my only option was to take a break for however long I needed and then slowly rebuild my life again. It takes a long time, and I'm in the process of rebuilding again.
My psychologist and I were talking today about how we need to work out why I can sometimes do things and other times I can't do them, so that way I can work towards being able to do them all the time. Maybe this is something you need to consider as well? What was it about this situation/activity that made you feel anxious?
Kaitie.
