Wonderful advice here!
Trust me, you are right where you are supposed to be.
Your body, mind and spirit are probably still in shock.
You do have a personality and as someone said, it is probably great but be gentle with yourself, it will come. In the meantime, breathe and think in terms of a gratitude list when you get in these situations. That is, mentally start listing all the wonderful things you are grateful for, being sober, in that place. For instance, you don't have to worry about embarrassing yourself, you can eat 2 pieces of cake because you have not had 1,000 calories in alcohol, etc.
Keep it up, it does get better!
