I really can't help it, but I am really self-conscious.  I wish I didn't feel that way.
It's very common!  Maybe you're shy, unpleasant feelings of self-consciousness are associated with shyness.
Yeah, I am a little shy and definitely not by choice.  I can't help it.  What can I do to overcome this?
It could mean you have low self-esteem.  Why would that be?
I don't always think I am the smartest or have good confidence.  Maybe I should see a shrink?
Talking about it could be very helpful.  It's not your fault, some people are continually more self-conscious than others.
Oh!  So it may just be genetic than, right?
It could be, but even so it could hurt your ability to perform complext actions.  Getting help is a good idea!
Why would it hurt my ability to perform complex actions?
Because you become overly aware of every tiny action, making it very hard to focus on the big picture.
