For some reason, i don't feel good everytime i go to work. Like there is something whispering in my mind "why bother to go there? They will just joke on you like every time". I don't know about it, but yeah, i feel so tired and having this kind of anxiety attack everytime i'm going.
Am i having a severe depression or it just a normal thing in work?

Social anxiety is a pain in the ass.

It could be stress, it could be depression
Don't try to self-diagnose, please try to find a psychiatric or psychologist
Or talk to someone u could trust
If u got an attack, deep breath and squeeze smth in your hand (something soft like clothes, or something else)
You can talk to me if you want, maybe reach me here or something
I hope you can get well soon

Thank you for the response, i don't know why. But maybe it could be the problem with my current workplace, maybe because the people that too demanding that i feel so stressed when they said like they disappointed in me. I just confused about it.

It could be a problem with your workplace, yes. But it also has to do with what you are feeling and thinking; how you're perceiving reality.

It's not a healthy place for you because they just mock you. But you can try to go further and try to understand why they do this. What is it in you that makes them behave agressively towards you? Answering this can probably make you realize something in yourself that can be improved.

Of course, this does not mean you need to necessarily stay at your current workplace.
