I'm kinda afraid to go to the office tomorrow...

Because my senior told me I'm having a bad manner, that i was too confident, that i was underestimate everything...

While I'm just being confident of my job, or else i would no longer work. I didn't mean to underestimate everything as i said its easy because I'm used to it, it's my job in the past of 5 years and going through a lot and i confident to work on the field.

But my senior said I'm having a bad manner for being confident... This is my first time in my life people call me having bad manner while all this time people praise my work...

I do hurt inside, as she only knows me for less than 2 weeks to say it like that. I'm having a mental breakdown thinking i may offence her in the future and afraid from being confident...

How i should do?
