<human>: Can you condense the text into a few key points?

Since however long my mum has had a problem controlling the amount she buys and this kind of leads to hoarding. We are a family of 4 but we have enough food and household supplies to last us years. Most of the food is out of date or on its way out, fresh foods get thrown away. It is a complete waste of money.

My dad gets angry over it, which is understandable. She spends his hard earned money wastefully. He probably shouts about it everyday but she never listens.

I asked her when it was just us two alone 'Do you want some help with this?' but she said no so I asked 'Do you think there is a problem?' she says no. She always tries to make out like she's buying less and the problem is solved but it's not.

It must be a mental problem right? There must be a reason why she feels the need to buy so much all the time? But I can't get her therapy or counselling unless she can admit she has a problem. What do I do?
<bot>: my mother buys things wastefully permanently causing tension in the household. She denies any problem, how can I get her professional help?
