My mum worked and I'm not fine. But I don't think it was anything to do with her working, more that she's a mad old bat
She had 2 jobs from me being about 10ish, and left at 5am so I had to get me and my sister (3 years younger than me) up and ready for school, (dad was either at work too or asleep in bed depending on his shift) and she had another job which meant she was out again when we got home from school. She'd done dinner and left it in the microwave and she got home about 930pm. Again, dad either at work or in bed.
She did what she had to do, more power to her elbow and all that..she must have been knackered and she did it all to help support us - dad at that time was a miner. He did 12 hour shifts, and when he wasn't working he was in bed because it was knackering back breaking work!
But I have to be honest, it felt horrible to get up and my mum not be there. It felt awful to go home to an empty or quiet house. I understand now why it had to be the way it did, but at the time I didn't. All I knew is my mum was never there. It was horrible to not have my mum there and to have to sort myself and my sister out every day. I do remember that I wished she didn't work.
Did it screw me up long term? No.
