I am scared of losing of my husband after my father died. how do i cope with this fear?

Separation anxiety: This fear is pretty normal, particularly after an event like this. You've already taken the first step and acknowledged that the fear is there and your trying to cope with it. Talking it out is usually the first helpful step. You can discuss it with a friend, church minister, or your doctor, who can all provide good listening. If it becomes severe and interferes with sleep, medication may help.
