Shyness

Much ink has been spilled on the topic of shyness and social phobia, which it sounds like you may be struggling with (although lots more information is needed before a diagnosis could be made).

Whether or not your particular problem is severe enough to warrant a diagnosis, I believe you could benefit a lot from seeing a counselor to help you deal with this. A trained professional could help guide you through the steps and work with your individual needs and strengths.

Self-help books are great, but they can't replace a human being who can give you the personal attention you need.  Your problem is not insurmountable; you just need the right kind of help.

Good luck, and feel free to contact me if I can be of further help.
