Social anxiety, any advice?

So I just started my new job at a fashion clothing store (forever 21), & I have a hard time trying to make friends in general, I feel like I’m so awkward 🙄🤦🏼‍♀️ I know everyone is super chill & nice but my social anxiety just stops me from letting loose..

Any advice ? 😕 (I’m a cashier so I’m used to putting on a fake costumer service persona lmao) but when I have to be myself around people my anxiety just kicks in

I really don’t want to be seen as that “new girl who doesn’t talk to anyone”
