I have to mostly agree with iride. I don't want to steal your joy at all. I know exactly how you feel. It hasn't been that long ago when I acquired my first horse, so I know very well the feeling you have in your heart.
I also know that things are much more complicated than they seem when you get your first horse. I had so much fun with my horse for a while. I soon learned that I had been accidentally ruining my horse with pretty much everything I was doing with him. I did not learn that, though, until he became a huge problem.
Every single time you spend with your horse you are teaching him something. The thing is, if you don't know what you are doing, you will often be teaching them the bad stuff.
I don't think it is hopeless, though. It just depends on how much you are willing to spend on it. I think you need a trainer now. Have them show you the ropes and to help you deal with problems that may come up. You will be amazed at how much you learn.
