Yeah, I agree...I don't think that inheriting it is the ONLY way to get it, but it seems as though it can be a component. Both of my parents have anxiety, and a mental illness is common in my family in general, so I can see how it could be partly genetic.

I think environment is important, too, though. My parents were both anxious individuals, so I probably learned a lot of behaviours from them, along with inheriting their genes.
