Put your Cessna away until you learn to fly with other RC airplanes that are much easier to fly and more forgiving when you make a mistake.
The easiest RC airplanes to learn on and the kind you want to start out with are airplanes that do not have ailerons. You put both the rudder and elevator on the right stick of the transmitter. Find out who the people in the local club are who are qualified to instruct. Some clubs actually have certain things that a person has to pass in order to be an instructor, other clubs do not do this.
After you get good enough to fly a RC airplane that does not have ailerons an entire flights with out an instructor then move on to flying something with ailerons like your Cessna. You put the ailerons and elevator on the right stick of the transmitter, and the turning, and control of pitch up and down with the right stick is very similar to flying the trainer that had rudder and elevator on the right stick, except that is is much easier to roll the airplane too much now that ailerons are being controlled, so the experience you acquired from the trainer without ailerons will help you not over control when you turn, and also you will know how to put the right amount of additional up into the elevator as the airplane turns.
Also, as someone has already mentioned, you can start with a very low cost RC car to get use to the reversing of controls when it is coming towards you. After you get that figured out move on to a RC airplane that does not have ailerons.
If there is a good RC airplane hobby shop near you ask what is available in an RC electric trainer without ailerons. If there is no good hobby shop near you call Tower Hobbies. They have a big web site and are one of the biggest internet RC airplane hobby shops.
As someone has already mentioned you will have to join the AMA to get liability insurance before any club will allow you to fly at their field.
When the airplane is making an approach towards you and descending to do a low fly by, or to land, the left right will be reversed. The easiest way to get use to this after you have practiced with a RC car, is to stand in the center of the runway (if your club allows) and align the airplane to come right at you (but keep it high enough to fly safely above you, like 100 ft. above). You will notice two things. If the plane gets off of the center line if you move the stick to the side the plane went to it will bring the plane back to the center-line of the approach, and also when the plane is directly over your head in the instant when it goes from towards you to away from you, you may panic and wonder what you should be doing with the control. Do not put any right or left control into it at this time, just turn around with your feet and fly the airplane away from you.
Now here is a tip on how to maintain the proper glide path (rate of decent) as the airplane comes towards you and you want it to get low enough to land. Look at the thickness of the airplane wing as it is in a decent. The wing will look very thin almost like a pencil line as you can only see the leading edge. If that thin line becomes thick it means the airplane is either diving or climbing too much. Hold that pencil line until the airplane is at the height you want it to be at when it will fly over you. When it is at that height give it a little up so it fly's over you. If you hold the decent with the wing being a pencil line all the way to you, you could actually hit yourself in the face with the airplane. Once you are good at making descents just make them with the plane lined up to the center of the runway and give just a very small amount of down so the pencil line of the leading edge is just a little bit thicker so the plane gets low near the beginning of the runway.
