I am absolutely crippled with regret. It's not something I can learn from as the opportunity has passed. I torment myself with going over and over what I should have done. I know I need to stop but I can't work out how. Does anyone have any tips for dealing with regret? (My main one relates to not staying split up with DP when DD was small, plus also a million other smaller ways I'm convinced I've done the wrong thing).
