I knew a lady who had a really good start in life. She was born in '54, so whilst things may have been very different then, she was an only child and as such, was provided with quite a good upbringing. She was very intelligent, and went to an all girls Grammar school. She was extremely free-willed, and her job as a librarian didn't excite her. She decided to travel instead.
She met a man, married him and had 2 children with him. It was great at first, but her husband worked abroad a lot, and earned a decent salary. With that came a dependence on alcohol. She divorced him eventually!
She remarried and had another child. So 3 children to 2 different men.
She died at the age of 47 from cancer.
That lady was my mum. I could not be prouder of such a more kind, compassionate, inspirational and truly wonderful woman. Her life might not have panned out the way others thought it would, or indeed, the way she thought it would, but in her short time on this earth, she accomplished so much. She never became solvent and she never ended up realising her dream profession, but what she did do was to be a fantastic parent and a great friend. Everything she desired happened.
I don't mean to invalidate how you feel, but even if you live until you are 90, life is far too short for you to give a shit about what others think. You do you! There is no real script. Be a great mum and friend and you won't go far wrong. Oh, and whilst you still breathe, you can do whatever you want
