Im 12 and hate my life:( ?

Ok so thers a groupnof people at school and they are bullies. They hit me call me retard, fat , ugly, stupid, cow, 2yr old, and thats just the tip of the iceberg. No matter what i do they find a way to bully me. Whether its by exclusion, or saying somthingthat anyone but me would think harmless. They even trash my stuff. Telling people hasnt worked even though i told everyone. Some days i feel suicidal which now is most daays. Plz quick responses as i leave for a vacatuon for a week or two and wont have my ipod or computer. Thx in Advance.
