You just recently acquired Johnny, have been having some issues with him already, working with a "trainer" to solve those issues, and throwing various other things at him.
You need to be in an environment where you two can build a bond and trust and stay there for a while. You have a young horse with a lot of energy that needs to be directed somewhere. Direct it towards building that bond.
This is a time that you need to be spending literally every day working with him -- not turning him out in pasture until that bond is formed.
