I'm 15 years old and a girl and for the past 2 years now I seem to always be angry at everything and every one I don't mean to I don't want to be to but I don't know what could be the matter like all of a sudden I will be happy and fine then out of the blue I will get all angry and I'm starting to loose my friends and its really affecting my school work and stuff so do you have any ideas what could be wrong?
