I have social anxiety disorder. It's an anxiety disorder characterized by a significant amount of fear in one or more social situations.
I'm sorry to hear that.  What type of social situations are the most distressing to you?
Triggers can be perceived or actual scrutiny from others. Basically all social situations can be.
So, if all social situations trigger anxiety does the disorder result in agoraphobia?
I'm not sure, but my social anxiety causes physical symptoms often including excessive blushing, excess sweating, trembling, palpitations, and nausea.
That does sound debilitating.  Do you leave your home often?
Yes, but I make concessions. The disorder is sometimes referred to as an "illness of lost opportunities" where "individuals make major life choices to accommodate their illness".
