Replying to So am i basically gonna get raped in the ass by karma?

okay, so today in chemistry i realized I had left my hw at my house.  later in class, after everyone handed in their homework, the teacher presented two homeworks that had no name on them.  the first one was claimed, the other one was not.  so i claimed it as mine, and put my name on it.  it wasnt mine...but i didnt want the teacher to get pissed that i didnt have my hw. 
i honestly feel terrible about what i did, although should i feel too badly?  because no one claimed it. 

please dont hate, i know this was a complete d-bag and stupid thing to do, and i feel terrible about it. 
any good plans for getting karma back on my side?  i dont know whose it was. 
thanks newschoolers.  and please dont tear me apart, i know what i did was horrible.
