What you are describing sounds a lot like Pica, a disorder in which an individual will crave non-nutritive substances (a.k.a. things that aren't usually considered to be food).
The cravings you describe are all common within the disorder; the presence of pica often suggests that you may have a mineral deficiency. In many cases this mineral is iron, which can be found in most of the substances that you named. Your instincts take over once your body becomes aware of this deficiency, causing you to crave materials containing the deficient mineral. Unfortunately, as these substances are non-nutritive, eating them won't do you any good.
Pica can also be a sign of a mental health condition. My best advice to you would be to visit your doctor, a nutritionist, or a dietitian and explain your symptoms and their duration as best as you can.
Best of luck!
This is a mental disorder. You should talk to a doctor who handles mental parts of the brain. With the right trreatment these cravings should stop. Please speak to someone as soon as you can because if you wait and act on these cravings it can lead to some serious health problems.
You're obviously turning into a larvitar.
