I know that feeling, but a feeling might be just that. Now this is going to be slightly hypocritical of me and I apologise, I'm no good at following my own advice but the only way to not be behind that wall is to get round it and talk to people, integrate into the world, become a part of it. I'm only just starting to try and socialise more, get out of my bubble and interact. I have made an acquaintance at my daughters school and hope to turn it into a friendship. I don't have many as I isolate myself way too much. But I want to try again. Just got to be more careful in who to trust.

Hope you feel better soon
