I had a similar feeling few years ago. What worked for me: Meditation. Why? Because it stresses on the now. It's practical too. There's nothing you can do about the past. And sitting and internally whining doesn't help. Do whatever you're doing now and give it 100% attention. In the end, if you're lucky, you'll realize the futility of it all! :)
