I just joined a private enterprise, I found that my colleagues are very outgoing, often joking and playing with each other, but I am a little bit unable to let go, I always feel awkward.
As a newcomer in the workplace, I am always unconsciously cautious, and I am always polite to anyone I talk to, for fear of saying the wrong thing. And I'm so sensitive that I easily feel lost if people don't respond to me in time.
What is the best way to adjust this situation?
Hey, buddy! I'm so glad you're here.
From your brief sharing, I can appreciate your troubles as a newcomer: you are a little bit unable to let go of your new job, overly sensitive, and easy to lose your head because of your colleagues' lack of response.
As a big brother who has been in the workplace for over a decade, I can tell you with certainty that this feeling couldn't be more normal! Many newcomers go through this phase when they first join a company, and I was the same back then.

Don't worry, all these worries will disappear naturally with time. Let's relax and talk about the reasons behind it.
When most people enter a new environment, because they are unfamiliar with everything, the brain automatically turns on protection mode, keeping us alert to our surroundings.
You have just joined a new company, subconsciously worried about saying the wrong thing or offending people, so you speak in a coy manner, always want to show cordiality and friendliness, which is a very natural psychological reaction.
As a newcomer, you are eager to quickly integrate into the team and be recognized by everyone, so you are particularly concerned about others' feedback. Once you don't get a response, it's easy to catch the signals of being ignored, thus creating a sense of loss.
These are common mentalities of newcomers to the workplace and there is absolutely no need to beat yourself up. How to regulate it? It's actually super easy and you can definitely handle it!
⒈ Objectively speaking, as you become more familiar with the company and colleagues, the tension caused by this unfamiliarity will automatically ease, so do not be too anxious about the current state;
PEAK Subjectively, focus your energies on your work, acquire business skills as soon as possible, and improve your professional competence. Concentrating on your job is the best way to earn respect and integrate into the team;
ᴡ Mentally, relax and don't be tight-lipped. Keep your original style of speech and behavior, as long as it is in line with the workplace etiquette. Generous and natural to do their own, than forced to imitate others is more important. Colleagues like to joke, you do not have to force yourself to do that, just go with the flow.
The emotions you are feeling are a normal reaction to the transition period, so don't be too concerned. Once you've adapted to your environment and your work is up to speed, these worries will naturally dissipate.
Good luck with your work and feel great! ◕‿◕.
