Hi thanks for your approach. I understand with your statement that, you might be scared of some thing related to your personal or professional, if you know the reason for afraid, have you any time tried to overcome of it. if not thats obvious you can't concentrate, sleepless, you might be feeling difficulty in handling various things in life. the anxiety and stress towards anything will lead to problem in different areas of life. its better you concern any psychologist in your place and I am sure they will help you to overcome this issue in a positive way. take care.
