Tiny objects that add weight?

I have a weigh-in today, and I need to gain at least a kg. I'm pretty sure I lost, since i haven't followed my meal plan, because there has happened a lot of bad things this month (Death (s) and a divorce in my close family)

I have a binding around my arm right now, so I might be able to stuff it with something - not too obvious.

Please, please, PLEASE help! I already drank one liter water, but I fear it isn't enough.

Please don't judge me. I'm a human, I make mistakes and I know that I should have followed the stupid meal plan, but I just lost my entire appetite after the horrible news.

A short explanation :
I have anorexia - however I do see myself as a recovered (I've had for a good five years now) and since I really haven't gained more than two kilograms during the entire years, I need to gain now, or I fear that they'll put me in daycare of inpatient.

My metabolism is extremely high - it has always been high, even before my more server anorexic phases. So even though I struggle with gaining weight, I still have to gain before they'll release me, if so to say.
