im the fat girl... and that was more than a year ago so i propably weight more now...

how does a girl like me get a date? im in highschool and im terrified that i wont get a date for the next dance (january). now DONT tell me not to worry or to go with friends!! and dont tell me looks dont matter! theres guys who date skinny girls and theres chubby chasers, only i have no clue where to find those(and how to identify them).

oh yeah and dont tell me to randomly ans some guys out, im way too shy for that. now id love to make some more friends too, im new at my school, but theres not really a wide range of clubs after school... what should i do? its not like im wandering around school all depressed or something... im a very positive person (i know i know, but i really am!), im just no too much into starting conversations with "strangers", too shy for that...
