Its a big place

This world we live in, its a mighty big place. i don't see much more ahead of me other than the view room my bedroom window. i dont really go anywhere. i cant see myself alone is this world. how hard it will be , i just dont understand how will i keep my feet firmly on the ground.how do people do it. i only feel fear. you see things our on the news, murders,deaths & pain for all the world and in the security of your own house you think you will be safe....
