Is it normal to save food trash, and wrappers?

I'm a 19 year old college student, and I live at my house. But I have a problem. I love eating tuna, and sometimes I eat excessively. Like, 3 packets at a time. I binge and purge, because I don't have a lot of time to eat a proper meal. After I eat a lot, I'm afraid my roommate will see the empty cans and packets, so I hide them all over. I think I do this for two reasons. I like the smell, and it gives me a thrill when it doesn't get found. I'm afraid my roommate will find them. So right now, (that I know of) I have one in my pillow case, two in my walls, one under my mattress, and a few hiding somewhere in the rec room. I know this could attract bugs, but they're accumulating so fast! What should I do? IIN?
