At work some people look so uncomfortable talking to me when I serve them. Maybe I'm being awkward, I mean I feel a bit nervous but I still try smile and try my hardest to be as nice as possible
You're focusing on yourself too much. When your attention keeps switching between the person you're talking to and how you imagine you look through their eyes, then how you sound, then back to them, then how awkward you feel and worrying if they feel awkward, then back to them, then "SHIT! AM I SMILING?". It's disorienting as fuck. Of course you're going to feel uncomfortable and anxious. I had a semi panic attack just writing that!
Try to focus outward and project yourself instead of inwardly and analysing yourself. Just focus on the purpose of the interaction. The mind has an annoying habit of complicating things. So simplify it. All that's happening is you have to give these people information that you know. They don't care how perfectly it's delivered. They're not there to judge a most confident waitress competition (I'm assuming you're a waitress). Their focus is on the information you're giving them. So you just do the same. Know what I mean? Like, you probably have an image of a perfect waitress in your mind with a natural big smile that shits confidence and you're trying to act like that. Well, fuck that bitch. She's not a real person. It's just a character some are good at playing. So you're not an awkward person, you're just uncomfortable being that fake. That's not a bad thing in my opinion. Try smiling with your eyes instead of your mouth, it's less effort and it looks more genuine and don't worry about fumbling or saying a word wrong, that shits funny. Just chuckle at yourself and BAM! You're instantly more likeable!
Anyway just remember you're far from the only person that feels awkward in these situations, the vast majority of people are uncomfortable around eachother because we are too protective of our reputations and it stops us expressing ourselves naturally. So we're all just wandering around acting like what we assume other people expect or want us to be. It's an empty depressing feeling. Unfortunately we role play all the time depending on our surroundings, we just don't really notice it until we have to play a role we don't feel comfortable playing. Then it's a cringeworthy nightmare! But if you try to forget about being perfect then it definitely takes the edge off ๐.
Just don't be too hard in yourself because nobody is judging you as much as you're judging yourself.
@Itsprincess: Haha well my advice is always amazing so if it doesn't work you must have done it wrong๐. As long as there's a few signs of improvement then you know you're heading in the right direction, and my advice wins.
