Your self consciousness could be the result of your thoughts.
Thinking →Feeling→Action(Behavior)
One quick and easy way to change this would be focus your efforts on changing the action(Body language for instance) instead of attempting to work on your thoughts.
Your thoughts with respect to self consciousness ( what others may think of me etc) are the results of previous experiences and beliefs that you have accumulated over a long period of time.
Rather than trying to change all of that, which can be a long drawn out process, work on your posture,gestures,eye contact and tone of voice. Try power posing to enhance your confidence levels and bring down your stress/anxiety levels.
This is called the As-if principle. According to the As-if principle,behavior causes emotion. Your body has the power to change your brain. Use it !
