If you're scared of losing someone you love because of your stupid actions what do you do? Muster up the courage to face it? Or do you cower away in fear of the pain of loss?

If you did something wrong or offensive to this person, simply apologize to them. If this person truly cares about you, he/she will forgive you, might take some time depending on what happened. But apologize, take whatever you got coming good or bad, as having that on your conscience will make life harder for you. Good luck!
