What have I done? =/

Tonight, I was doing work at studio with group mates......
Well.........
I am extremely pissed off with all those so called group mates........
I wanted to blurt everything out.......
But at that moment nobody is there for me to reach out........

Yet my mom called asking me how's everything going on.......
I wanted to tell her everything is fine as always.........
But I didn't I blurt everything out........
How upset I am by them 2/3 of them are totally useless only know how to talk crap........
Childish like 5 years old kid............
The group leader is a so called 29 years old dude.........
He can suggest like put a flag pole on the model.........
COME ON LA!
The model isn't meant for such useless thing........
Ask him about presentation he can say still thinking.........
I told my mom how I hate this group and all.........
While I am talking she is listening, quietly........

Oh well.......
After I tell out everything and I gets more comfortable......
But I heard her voice like starting to change........
Then before she hang up.........
I thought I heard her crying.......
Well I think I heard her crying.......
I just realized right after that call hung up I just made her worried bout me..........
I don't want her to be worrying bout me.........
That why I cover up most my feelings up.........
What I have done now just made her more worried bout me.........
Not sure if she can sleep well tonight.........
=(
Intense upset...........

Because of those fools........
I made my mom cry again.......
I want my mom's tears to change to laughter..........
I am such a failure am I?
Someone who makes mom worry bout...........
=(
