<human>: For the last several years, my mom has been completely devoid of joy and has admitted to being depressed.  She is overweight, is a hoarder, and finds little joy in anything, even her hobbies.  I believe her main problem is that she turns fun things into stressors.  For example, she is quilter and she has 42 unfinished projects sitting around.  

I'm only 15, but I embrace many concepts of minimalism.  I've tried helping to organize and throw things away but she usually gets extremely angry at me and yells at me whenever I do.  It's very frustrating since we both live in the same house.  What can I do to help my mom?

Give me the gist of the text in a nutshell
