Binge at LW

I am finally at an UW/LW. 5’8 and 102lbs, 15’sbmi. I have been maintaining this for a few months at a pretty high calorie count (1600-1700).

Went to the dr about my lost period and she said I needed to gain 20lbs MINIMUM. I don’t want to gain weight but took it as a “permission to eat” a bit since how bad can it be if I gain a pound or two. Now it’s been two days and I’m literally SHOVING food down my face as fast as possible. Easily 5k yesterday and today.

Obv feel like shit. How noticeable to others is the couple pound weight gain going to be? I don’t even really care so much about being about 105 after this but embarrassed that my BF will notice and be like “how is that possible”

I’m hoping I have hyper metabolism due to LW but know I won’t because I haven’t been restricting/taking electrolytes and vitamins lately. I hate myself for being like this. I honestly could eat so much more rn but trying to break the binge & freaking out.
