Shopping?

The theme/subject/topic of my final exam is "How to resist the temptation of shopping?". This themetopic is not easy for me since the truth is, i don't like shopping very much and i'm not that kind of a shopaholic. I can control myself, so i don't have any problem with shopping for things.
So, how should i finish my final exam ?
First, from searching on the Internet...
I was amazed to find that there are so many sentences like "some professors said", "some doctors said".  (punctuation - written formatting rules for punctuation are pretty simple.  Leave a space after punctuation! And not before!)
It turns out so many people have shopping problem! (What relevance has your internet search with the topic here?)
I still remember my parents were worried about me because i didn't like go out (...by myself) without my friends -  that means meaning that if my friends didn't call me, i can't would stay in at home almost a whole week. Some people think that indicates a kind of psychological problem illness. But i don't think so, I just like singing, dancing, and painting. I like doing these things at home and I feel happiness and some kind of peace.
But what about those people who shopping ALL the time?
I'm thinking they just want to fill the hole of the in their heart, they can't satisfy their psychological desires, so they choose to buy all the things they want, to satisfy physical desires.
Above These aren't really my opinions, I Just want to improve my english.
Don't be too serious.
Thank u !
