New job jitters

as

I started a new job today and man oh man do I not fit in at all! Which has me so stressed out, on top of that I feel like an idiot. They have all been there over a year and here I am coming in knowing nothing and they expect me to know everything... I’m so scared they’re gonna hate me or regret that they hired me. How do I get over this and make myself feel better and like I deserve this cause I know I do and I know once I know more and have practiced I’ll get better, but till then I feel so stupid and dumb and like I never wanna show my face again. And the real kicker is I didnt even mess up, I just kept overthinking super simple stuff and making myself do stupid things or ask stupid questions. I seriously hate this and miss my old job and coworkers.
