Back and forth and back and forth

Got super depressed and changed from only eating barely 500kcal a day to eating ice cream 24/7 and gained 20 lbs in one semester, i went from 125lbs to 145 but before that i was at 115 and i found out I got cheated on and then went back to 125 so my hope is to get back to 120 lbs and get some abs :P
 
10lbs more to lose out of a total of 45
hopefully once i get to 120 i can work on maintaining and not binging and not restricting
