yamileth perez

hi my name is yamileth i'm 15 years old, i don't know how to start but i always see my self ugly and fat, i always think every other girl is better and prettier than me...it makes me really mad and sad at the same time i will cry just thinking i'm fat even though every body says i'm super skinny.
and when ever a guy compliments me i always thing they're lying i wont believe them and then they'll get mad at me for not believing them..but its just me that i' always think negative i really need help.
i dont eat anymore and if i do i get upset with myself i even started throwing up...my stomach will feel empty
sometimes i feel pretty...but its just like a dream...i say very negative stuff to myself that i probably shouldn't be saying i just can't help it
the mirror is my worst enemy...ill cry just seeing myself on the morror
im sorry but i really don't know that much english please help
