when did it start?????

i was thinking about my ED and i've been trying to pinpoint when it really started.....i remember when i was 18 and taking some classes at the coomunity college.....i wouldn't eat anything until dinner.....i wouldn't eat.....i would have stomach pains, but i was okay with that.....then that stopped.....i usually wouldn't eat breakfast or if i did it was something small like a granola bar.....or i just wouldn't eat breakfast.....sometimes i would eat breakfast and then have one thing for lunch and then have dinner.....i dunno i'm just trying to see when it all started......i mean i purposefully restricted on other days before i went inpatient....and then i totally restricted and stuff.....i dunno....it's weird and i really wanna figure out when it started!!!!!! i guess that's my topic for therapy on tuesday....
