Life is not for regretting. you can't change the past, so don't try to. you can only learn from what you have or haven't done. your past doesn't make you a bad person. people make mistakes. you are only human. you will die eventually. when it is your time to go, do not remember all the things that you should or shouldn't have done. do not count them, only acknowledge them and accept them now. your life will not end because of them, only change. the memories of actions and words can be dulled, but your emotions will stay with you forever- make sure they are the ones you want to keep. there are no "take-backs" in love. forgive yourself once and for all. let it go. live your life. No Regrets.
I wish I could take the advice in this. I have been doing nothing but regretting some of the things I've done in my past. I've been doing this since November and I went into a deep depression. Lost 10 pounds from not eating/sleeping. Wise words in this work.
Regret is a pointless..counterproductive emotion UNLESS you use regret to facilitate future change within yourself.
