Evanesce

"Of all the emotions, guilt is hands down the worst. Guilt and regret go hand in hand, so in essence, with the feeling of guilt comes the feeling of regret. When regret comes into play all the 'What ifs' start to cloud your mind. You're constantly reminded of that one minute detail or thing you could've changed. But you can't change your past. You're stuck with it and will be for the rest of your long lasting life."
