So many people mention this idea of "finding your instrument." The idea that you will try many instruments, and finally you'll pick up one particular one that just clicks with you and you have 'found' the instrument that you are apparently meant to play forever.
I don't think it works like this. I have dabbled in many instruments but I don't think I have one particular 'one' that suits me. Usually the ones that I am better at are the ones that I tend to practice more!
Sometimes I also find that if I hit a plateau in my learning I often get the same dejected feeling you seem to have... I feel that I am not very good and feel unmotivated to play or learn more. The key to getting that enthusiasm back is to just keep practicing and trying until you master a new technique for example and feel that buzz again.
