I Fed up vs. Im Fed up VERY DIFFERENT MEANING SHORTS

In English, these two phrases 
which are almost the same have very  

different meanings. If you say “I f*cked up”, 
that means I messed up, its like an apology,  

it’s acknowledging you did something wrong. 
“I fcked up” or “I fcked that up” or  

“I completely fcked it up.”
But if you say, “I’m fcked up”  

and instead of I you say I’m, then you’re saying 
I’m really drunk or I’m really high on drugs. 

I’m so f*cked up.
Two very similar  

phrases but very different meanings.
Quick add-in, if you don’t want to cuss,  

you can say “F’D up”. “I really F’D up, I’m so 
sorry.” or “Woow! Last night I was really F’D up.”
