Always remember that in someway or another you're somebody's angel, even if you don't know it. They love you and think of you even if you don't hear it everyday. Trust that there is love all around you even if you cannot feel it. You are not alone!
Be kind to animals... they weren't created to be abused, neglected, mistreated, destroyed, used, etc... besides if a person can cause harm to an animal for no legitimate reason, then I shudder to think what else that person could do to others.
