You are talking about the
Seven deadly sins
You did well and you are full of me, but you might have to swallow me to keep on going.
Pride. You are proud after an achievement. However, when you make a mistake, you have to swallow your pride.
Don't get all green over me, just take it and be done with it.
Envy. Refers to the phrase, green with envy.
You can scream all you want but without the anger I give you, you'll just look silly.
Wrath. Often characterized by anger and screaming, but can even be expressed by its absence through throwing a fit.
If you can't decide between a pie and a cake, just use me and your problem will be gone.
Gluttony. A glutton wants to eat anything and everything.
Don't look at me like I'm creepy, you're alive thanks to me!
Lust. Lustful looks are often considered creepy by the recipient of them. But lust is the reason that leads to procreation and our birth.
What's so wrong with always watching TV, can't you just let me be?
Sloth. Sitting on a couch and watching TV is a common form of laziness.
Generosity is just silly, just give me your candy!
Greed. The opposite of generosity, and wanting what others have.
To explain the last line,
I am the sum of all above me. Don't underestimate me for a fatal mistake that might be.
Together these are known as the Seven Deadly (fatal) Sins (mistake).
