We all have regrets over one thing or another when we get to our age - it is normal to feel like that.
But, you have two choices: you can either give in to this, or you can look around for things to get involved in that you would not have any regrets about when you are 90, perhaps volunteering or taking up some activity you will enjoy.
However, I do not think that you have had a wasted life. We none of us have a clue why we were put here, but I always think that being kind to others is central - that does not involve careers and lots of money. As others have said, bringing up a lovely DD is a huge achievement and is an important a career in itself. I get very cross when that is denigrated. And what is wrong with cleaning? - another thing that makes me cross is denigrating practical necessary and vital work just because you do not need a degree to do it - what nonsense is this!?
And as to reading being a waste of time - I have therefore wasted a huge chunk of my life too!! - but I do not look at it like that! Reading is a huge pleasure - broadens the mind, entertains. It is a GOOD thing!
And as to good looks - lord above, this is the least important thing in life - and anyway, who says you are not good looking? What is good looking? - what the media say is good?
The media have a lot to answer for in peddling the idea that we all have to achieve, achieve, achieve - that is not true; we just have to live blameless lives and take pleasure in the small things. Why ever would you wish to make someone else envious?
Believe me those who we are envious of often cover up many sadnesses.
Go girl!
