People always regret what they have done, especially when things go wrong. People make a lot of decisions throughout lifes, some are good, some are bad, some are just fine. Though it was a bad idea, people just can not change the past, because thats the history. Sending you back in time, that doesnt help that much. You think you would do something different, you think you would make an opposite decision, you think you would not make the same mistake again, however, the result still remains. Some people think or call this is destiny. To me, thats just history, something I have got through, something I have done. Done is done. Time travelling can not change anything about it. Sending you back is letting you see things through, learn from the lesson, and move on. If you can change your past, then you are not who you are for now. You should be different, no matter better or worse. Rather than changing any history, growing up and doing things differently since then are more helpful, which will make the life better and easier. You can not change your past but you can always make a brighter future for yourself.
I'm not as lucky as Erica. I dont have a therapist who can send me back in time to check on my mistakes. I looked back, I regreted, I learnt, and then I realize that is how life goes on.
