Can a lot of crying cause ur lips to be chapped .iv been deppressed real bad latly, and would cry like crazy and plus my room stays cold.

Dehydration: If you are dehydrated as a result of crying this can dry up your mucous membranes and skin, and cause dry lips.

Please see counselor: Please see your school counselor or share your feelings with your parents or your pediatrician right away. The symptoms you describe may possibly be triggered by a medical illness such as low thyroid hormone (hypothyroidism) or mononucleosis--just to name two. But to answer this concern laboratory tests will need to be obtained. I honestly think this can be fixed. Please ask for help right away.
