Is week long binge and ten lb weight gain normal?

Im not sure if i have an ED but i know i obsess about calories a lot...except over the past week i went home for a school break and lost control. I kept eating when i wasnt hungry, ate syrup out of the bottle, donuts after donuts, decorative stale candy, candy bars after and before dinner, i was never hungry beacuse i was always stuffed to the point where i was about to throw up and couldnt move. I left weighing about 105 lbs and came back at around 114. Im disgusted at how i look and cant belive i did what id did? Im scared of gaining weight but im still not sure if i should ask for help i mean maybe its just a phase and then again my weight isnt low so idk im just sooooo confused =(
