Abandonment: the act of giving something up; desertion.
There is usually a clear cause of fear of abandonment. As human beings we all need people. Most of us fear being abandoned at some point. If someone's greatest fear is that they will be abandoned or that people are always going to let you down, then they will constantly be looking for signs that they are about to be abandoned.
I have a very real fear of being abandoned, of never being important enough to a person, of never being truly cared for. I worry that I will spend the rest of my life in my loneliness, never really allowing myself to grow attached to others.
Someone once told me that with God in your life you will never be abandoned or alone.
....but is that really true?
