I feel super awkward sometimes

Idk if yall went through this, maybe it just takes time to adjust. I like dont know how to act sometimes being completely sober. I get anxiety and im super fidgity and shit, which pisses me off, i dont want to be awkward but i just am until i get comfortable. Like I just got this new job and i started the onboarding and i was doing it with the owner, a very very nice older woman who reminds me of my mom, and she picked up on it and told me to slow down and relax and kinda calmed me down. When tf do you start feeling comfortable and confident and not having anxiety and being all fidgety.
