Phobia Support Group
A phobia (from the Greek "fear"), is a strong, persistent fear of situations, objects, activities, or persons. The main symptom of this disorder is the excessive, unreasonable desire to avoid the feared subject. When the fear is beyond one's control, or if the fear is interfering with daily life, then a diagnosis under one of the anxiety disorders can be made.
Are there neighbors you can get to know in case of emergencies? Perhaps you can start teaching your grandsons an emergency plan (even very young children have the ability to act in an erergency). I'm sorry you don't have someone at home to help you with your fear. I am new to this site also, but it seems like a special place with people who are willing to support you.
