That should not dent your confidence because you did the correct thing by going around.
Many low hour pilots make the same control inputs for each landing, experience teaches you to adjust sink rate and attitude according to the rate of descent in the roundout and flare to touchdown. The use of power to control rate of descent from the flare is also another tool not often used by low hour pilots. Consideration should be given to modifying technique so as to round out lower and get the aircraft onto the ground asap in conditions of shear/sink, this is not the time to prolong holding off, much better to accept a flatter attitude and get the aircraft on the ground and hold it there.
Shobdon sometimes experiences rotor from wave and it can be quite a suprise and very turbulent with hardly any wind in the sock.
