attention deficiency

I am 28 years old male with fair complexion, my height is 5.5 feet and my weight is 68 kg.
First of all I have sleeping disorder, I often feel that I have incomplete sleep, my sleep has no specific timing, for whole day and night there is no sign of sleep and when it came, Oh! My God, continuous 12 hour or even 18 hours, it seems that I have sleep as disease (hypersominia).
Second problem is related to my mind, I am very coward person, it seems that freight is located in base of my mind, I feel all kind of fears (height, riding, water, air rain, noise etc) and my every day life is strongly effected by fear or freight.
Third one I am slow beginner, I need a lot of courage to start any work even for basic necessities like taking breakfast, law of inertia is fit on my condition I need a lot of force and courage to start a work and also I am ready to stop any work.
Fourthly I do not have will power or power of decision.
At last but not least I have attention deficiency, main problem is related to my body, I have severe trembling shivering in my whole body.
At sitting position there is trembling in my head and in my hands, at standing position my legs also start trembling accompanied by head and hand. When I stretch my body there is trembling and shivering in every part of my body. These conditions become sever when under anxiety.

I need a remedy that is indicated when any one has feelings of weakness (not weak), trembling (whole body, every part of body specially head) , general debility, trembling from nervous weakness and mental dullness (being 'paralyzed by fear'). that is also useful when there feeling anxiety about an upcoming event such as stage-fright about a public performance or interview, or anxiety before a test, Fear of crowds, a fear of falling or other stressful events.
