Would you call yourself socially awkward?

When I'm uncomfortable around people I make the WEIRDEST faces. Like I scrunch my lips up, of do this half-assed smile, or duck lips. I feel so conscious of my actions that I dont know where to look, and I get flustered. And I laugh at everything, way too hard. I'm a happy, confident person, but I feel like I'm very awkward. Especially with people that I'm not close with, or men. Do y'all have tips on how to be more "yourself" around people? I went out to my friends birthday lunch today, and realized how awkward I was being. I feel fake.
