You probably overestimate how awkward you are and in particular how much this is noticed by other folks. Try to focus on what you do for other people, what you give them in your interactions with them, and how interesting they are to you as people. People universally like and appreciate being paid attention to, being taken seriously, being shown an interest in. If you can do that for people and I am sure you can, this will go a long way towards erasing whatever awkwardness you might have about you.
