Dear Abhishek,
It's a new place and new job. Everything is new for you. And you are new for office personnel. It's OK to have the feeling of trying to put the best impression first and trying to win everyones trust as soon as possible.
Also it's very natural to feel that everyone will be observing you.
How to ease your troubled mind. When that feeling comes that your manager is thinking about you or what will he be feeling about you. Tel yourself It's not new for him. It's new for you. He must have moved to another thought. And trust takes time n efforts to build n sustain.
Step 2- after coming back home. Talk to your frd . Just vent out. That way you will have a sense of support when you go to office tom. It will help you in adjustment phase.
Step 3- Remove the thought of thinking you are getting fired. Nobody gets fired due to difference of feeling of opinion.
Step 4- have milk before bed.
Next Steps
Abhishek adjustment phase requires learning of new skills. and practising them. you can do it.
