Binge purge

Two days of good eating. No binges, only food i consumed was some bread so my stomachk would not rumble during classes.
When i binge i almost never purge because I am not good at. Nothing came up even if i tried really hard. but the last weeks i binged and the times i tried to purge it acutlly worked.
So when i binge i have to purge to get rid of some calories and also to punish myself.
