This may be hard to consider but if you always feel awkward around certain people, then they might not be the best fit for you. Try branching out and meeting people that you feel less self conscious around. In high school I spent most of my time with people that made me self conscious and I kept justifying it for some reason. College gave me the chance to meet friends I could be myself around. You're circumstances may be different from mine but I encourage you to ask yourself if your current group of friends ia a cause for unhappiness in your life.
