there is no life without the mall

what do you do if you think your nine year old is depressed...i am not sure really but, she seems down so much of the time and doesn't want do anything...well except goto the mall or movies or play video games or wish we had a tv...maybe she's just stir crazy because it's the summer and she and i are the only ones in the house but, i offer to play games, go for a walk, ride bikes...go on a walk to take pictures, walk down to the square, practice cooking, listen to music, do art, read...anything she wants that doesn't involve spending money...because i don't have any extra this summer [i have no job]  this does no good...she is on the verge of tears and moping around and says that it's okay if we just go to the mall to hang out and walk around and window shop for hours and hours and hours...i was so excited about this summer and now i am at my wits end already and the summer has just started...wouldn't you rather walk around outside then in a mall full of crap that you can't buy

any suggestions about what i can do/???
