Fear starts from the mind before it conquers a person completely. Being unease, worrisome and anxious about one's future, plans or possibilities usually finds root in how much the mind has invested in fear of failure.

Intimidations, abuse, threat and pain can be the cause of fear most teenagers experience. But, it is possible to overcome your fears!
