I sort of actually agree with this. There is a difference between being depressed, and being a selfish, pathetic brat, and Haley was acting like the latter more and more as the season went on.
I often wonder if that's how she was written, or if Joy was just overacting. Either way, it rubbed me the wrong way.
I normally love Haley and can relate/connect to her, but not after her mother died. I've dealt with chronic depression for over ten years and have spent time with a lot of other depressed people and Haley acted more like someone who has histrionic personality disorder dealing with the loss of a loved one and I know Haley doesn't suffer from that.
I also HATED that she acted like no one else had ever lost a mother and wouldn't understand her. Okay, seeing as one of your best friends named Peyton, lost two, and you didn't even bother to talk to her about it, or I don't know your two sisters who were in the hospital room when she died know exactly what you're going through, seeing as they are your sisters. That pissed me off a lot. I just really hated her attitude after her mom died, and to me it was completely selfish and way out of line. She pretty much ignored her son, who just lost his grandmother, who sisters who were also dealing with that loss, treated Nathan terribly, and basically tried to kill herself three times, all because her mom died? Sorry, but you're not depressed, honey, you are being histrionic and acting like a child.
