I have made many mistakes in the past, with fortunately no ill effects at the present, apart from perhaps my own mind, and guilt for my past behavior.
I was a party girl prior to having DC, which carried on for a few years. I spent time hungover, which affected my parenting which I feel so, so guilty for. She had good people around her otherwise, which I felt would somehow justify my behavior (I know how awful that sounds!)
I'm teetotal these days, have built up a good career, and get on so well with my DC (though she compares us to siblings, so maybe I'm not doing things completely right!).
I am accused of pandering to her too much, which I think may be due to the guilt of how I used to behave
I have a lot of other regrets too, and wonder if I need to accept these as part of me are always there
