One of my therapists told me I was a social retard. Perhaps that would make me a socially challenged introvert?

One thing I will not do is allow someone else to define who I am. People can say what they want about me. I will listen, but I do not have to agree. For sure, I will be not be another's lickspittle.

Just because someone is an introvert does not make them insecure. I know my personality could use some work. Even so, to suggest someone like me has no personality simply because I am not as outgoing as an extrovert is a bit much.
