Pica: You likely have pica, due to iron deficient anemia. OCD is commonly described in pica as well. Best would be to see your doc for an exam with tests to substantiate the diagnosis and start treatment.

PICA: Your condition is called PICA and it may have physiological or psychological causes. Most common is low iron anemia, which may also cause you to feel tired. If medical causes are ruled out by your physician, then get psychologic evaluation and treatment to stop the compulsive behavior.

Agree with Drs P&M: Get tested for iron deficiency. Even without getting test, take oral iron and multivitamin supplements. Iron deficiency anemia is a likely explanation for your symptoms. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
