Friends Help?

Oviously she craves the attenton because she nows everytime she act's this way you will give the attention to her by trying to cheer her up or asking her whats wrong???Explaine to her "that feeling that way all the time is makeing her loose out on fun and getting her friends mad at her"....tell her you care and that you hate to see her so mad about something that is so riducluse to be upset about"....hopefully she will listen!...but anytime she gets like this pretend that u could care less what mood she is in...ignore it!....say o im sorry your in that mood"...and leave it at that she will get the hint sooner or later hopefully sooner!
