Big boys and girls do cry. A good cry during periods of stress can be a healthy way to bring relief to your anxiety, and it might prevent a headache or other physical consequences of "bottling" things up. However, if you are crying daily, seek a consultation with a counselor or a physician. This can be a sign of depression.
Alcohol and other drugs do not remove the conditions that cause stress. Although they may seem to offer temporary relief, these substances only mask or disguise problems. In the long run, behavior while "under the influence" increases rather than decreases stress. Prescription medications should be taken only on the advice of your doctor.
