To the point that I often did not want to leave my room. I found it difficult to be in a room with other people, eat in public, stand in line at the supermarket. It really affected my mental health and development of relationships.
I still have remnants of it now, in that I’m fairly quiet in social situations and not the most gregarious. But it has mostly gone away, to the point that I can go to events, even do occasional public speaking, and not really worry about it.
So I guess I wanted to say, if you currently have it, or know someone who does – you can definitely overcome it.
