An exercise that may be helpful to you is to acknowledge your accomplishments within your day regardless of what they are. Periodically throughout your day allow yourself to stop and acknowledge some accomplishment, some success that you have generated within that day. That shall be encouraging with you to be valuing yourself more and trusting yourself more, for as you acknowledge yourself you begin to build that trust within yourself and you begin to express more confidence. This allows you to express yourself more comfortably and to not concern yourself with other individuals’ perceptions or other individuals’ behaviors or choices.
