I'm tired out.
I don't even have time to catch my breath.
I'm freaking out.
It drives me crazy.
I'm losing my mind.
My head is going to explode.
I've had it.
I can't deal with this anymore.
You're working hard.
Take it easy.
Don't think about it too much.
Don't take it on heart.
Don't worry about it, just try to relax.
A: John, you look pale. What happened?
B: I stayed up late last night.
A: Did you have something on your mind? You look so concerned. Maybe I can help you.
B: Well, I'm under a lot of pressure. My manager is very pushy, he assigned me two projects. Now the deadlines are near, but I have finished neither of them.
A: Is there anything I can do for you?
B: Well, I guess no one can help me but myself. For the moment, I just need someone to talk to so that I can relieve my stress.
A: I know your feeling. Take it easy and say something to me if you like.
B: You're so kind, thank you.
