Horses are as different individually as people are, but in both there are some generalities that exist. Horses will respond to a firm, gentle, consistent hand, just like people will, unless there is something wrong besides discipline (pain, physical or mental health).
There are also as many ways to cure a problem as there are people to ask about it.
You can break a horse the old cowboy way and be riding him in an hour, or you can easy break a horse until he's 6 years old before you saddle him. Both will work. Just depends mostly on your temperament (and physical conditioning), desires, and purposes for the horse.
My take on what you originally posted is that you have a horse that is trying to sort things out with a new rider, a new stable, new horsey friends, new smells, etc. You also have a rider (you) who is trying to sort things out with a new horse, and you are a little afraid of him, by your own admission. Since you have some level of fear of what the horse may do, you are probably going to have to do the "easy breaking" method (metaphorically), in which you work slowly and patiently with your horse until either he winds up training you or you train him. Regardless, a horse should learn to be obedient to the rider even when scared. Especially when scared.
If it were my horse, I would likely put on a pair of spurs and he would learn fairly quickly that he must trust me and do what I say, even when scared or nervous. Not that I would be rough with him or with the spurs, but my experience tells me that horses learn quicker when the rider wears and uses spurs properly. To my thinking, quicker learning equals less time in the danger zone, for both rider and horse.
