Wikipedia has more on Eleutherophobia
Eleutherophobia is the fear of freedom. According to the bible, the fear dates back to the time of Moses. Eleutherophobia is very commonly suffered by slaves throughout the history, because many of whom may not know how to do right things when alone. Many sufferers think that it would require more responsibilities in order to be free and could panic if they do something wrong.
Symptoms of eleutherophobia include suspicion of others, a sense of servitude, nausea while thinking about freedom, social anxiety, tremors, difficulty of breathing and weeping.
Overcoming this fear requires understanding what freedom means and how it can provide personal and corporate liberty. A therapist can help manage the fear by explaining the prospects of freedom, and usually, your response has a lot to do on how you view these prospects. Changing the logic response and the fear response may follow.
