Do you think my Bulimia will go away on it's own?

i started being bulimic age 13, (now 21) was hospitalized and went through treatment at age 18 and was able to abstain for a while, but as time ped i soon reverted back to my familiar habits. i know that eating disorders among 30 yr olds and up are very uncommon. it is usually seen in 15-20 yr olds. (around that age) my umption is that in time the more important things in life take over and you slowly lose your disordered eating habits. Do you think that this will happen in my case? at this point i cant understand a life without purging, and i dont see myself stopping. but maybe in time it will fade away? i cant do this forever...
