Any situation in which I feel stuck and cannot escape -- this has largely been my issue with attending class, as I feel 'stuck' and then 'helpless.'

Getting car sick has been a really bad one for me in the past -- before I started having major anxiety issues and just had little attacks a couple times a year through out my adolescence (didn't know what they were), I would often become intensely 'car sick.' I know now that the spiral begins with me feeling a little nauseous, then restless, and then the discomfort and the fear that I won't escape the discomfort soon escalates into feeling very hopeless and very sick.

Saying the wrong thing to someone and being afraid that they're angry.

Lots of people and noise. This spring I went through a very bad period where just about any sudden noise in the house (someone suddenly speaking, a door open, hearing people enter, TELEPHONE!) would startle me in a such a way I would feel a wave of heat and prickling sensation wash over me. Te feeling would linger and if I kept getting startled it could build up until it was really bad.
