My Mum (may she RIP), used to swear sometimes that Women's Lib had done women no favours at all.
Back in her day, once you had children, the men earned the money and the women looked after the home and the family. Women were not expected to juggle all of that with also working full time in a stressful job, because quite frankly there aren't enough hours in the day.
It's great that women can now earn the same as men etc, and that there are no barriers to success, that was a wonderful outcome and she appreciated that, but let's face it, unless you can afford a Nanny, it is extremely difficult to keep all of those plates spinning and for something not to give.
I think I remember her saying, that the strapline for Women's Lib was that "women can now have it all", but maybe we were just being sold a load of shite?
Because that works if you are earning £100k+ with a fantastic live in Nanny, but if you are working 40 hours a week, in a low paid job and can't afford any help, the reality is that you are going to tits up at some point through sheer exhaustion.
I'm sure there are some wonderful men out there, who do 50% of the housework, laundry and cooking etc, but in my experience, men invariably do a lot less of that and certainly carry far less of the mental load, which means that women are burning out. Hey, but don't worry Gals, you now "have it all".
No real advice, other than could you go part time and reduce some outgoings? You are by no means a failure, you are a human being who only has 24 hours in a day!!
