Weird Eating Habits and Worries

Just to get it off my chest. Do you ever have a realization where it kinda hits you but lingers for a while? When I was a kid, I used to punish myself by not eating. I didn’t realize it was a form of self-harm. Fast forward to now I’m a healthy weight but I constantly worry about gaining weight. I have weird eating habits (like eating some paper, like cupcake/muffin wrappers present day, wanted to eat/lick/chewed on a bunch of stuff as a kid, etc.). I personally don’t think I have an eating disorder but I’m worried if I’m getting there sometimes. I don’t know if that makes sense
