<human>: Can you succinctly summarize the text in 1-3 sentences?

So basically I was a moron in college about a credit card and personal finance in general.  I kept overdrawing my checking account and getting hit with overdraft fees. There were no bank branches from my hometown in my college town, so I would spend money I had from home and not be able to deposit any paychecks from shitty college job to cover any difference.  While on the phone one day begging for another reversal of an overdraft, I ended up being talked into signing up for "overdraft protection" on my checking account.  Sounded like a good idea.  Cut to 3 weeks later and I get a credit card in the mail,  called to see what the deal was and apparently the "protection" was just putting the overdrafts on a credit card.  So of course, instead of being smart and cutting it up right then and there I used it for groceries, books, and booze thinking I would pay it off no problem with next semester's student loan.  Due to divorced parents fighting over who will co-sign for next student loan, I wasn't able to pay off for several months and it went to charge-off.  It has now been 7 years and I still see it on my credit [karma] report. 

Will this be there forever? Do I have to ask for it to be removed and how do I do that? How badly is this affecting my credit score?
