Should I bring this up at my next doctor's appointment

*******TMI*******

So I think I have pagophagia (and addiction to eating ice) because I eat 5 or more cups per day and my sister said I could only have 2 cups per week how but I found ways to sneak get some ice cause I cant stop. And when i don't eat ice i put bounty paper towels in my mouth and chew then spit it out. Please dont judge me because this is really sensitive to me. also I am 13 not pregnant (I say this because somewhere online it said that pregnant woman experience something like this idk)
