i don

hi im 17 and ive been experiencing problems with eating for over a year now. i go through (about 2 week) phases of restricting and starving and feeling euphoric when im making myself hungry. feeling euphoric when i step on the scale and see the number drop really fast. and then after those two weeks i usually start binging excessively and liquid fasting for days and days and then binging again...it goes back to normal after that and i dont have problems with food for a bit until all of a sudden its like this voice comes back and begs me to starve and start it all over again. sometimes after binges ill end up feeling guilty, take laxatives and start a liquid fast so i really dont know whats going on because its been a cycle for a while :/
