I only can think of your mum as your important life lesson. She might be like that because you need to become stronger more aware that nothing can take you down, wake up you inner animal ..
You know those hard life people who appear in our life’s are not to bring you down but to help you build up your strength. If your mum will cuddle you tell you beautiful words,clean your mess all around you and treat like a spulless prince than you will probably be an ashole in older years.

But thats only an idea. . Not necessarily true.
Wish you best.
BTW don’t put yourself in the ‘illness disorder cage’ try to analyse it from every possible perspective xx
