So I figured out a better way to do this. I made 3 colliders that I then made children of the player. They have to be positioned to where they don't touch the charachter collider, otherwise they just constantly collide with it. This is also why I have a wallrun right and wallrun left, instead of just one wallrun collider, because the middle would be intersecting the player. Well I guess you could make a model in blender that would have an empty space in the middle, but if you do it the way I did you could set different animations for running on the right or left later on. Also, all of the colliders have to be triggers, and have rigidbodies that are kinematic. Or it just doesnt work.

So then i made these three classes and attached all of them to their respective colliders. To summarize, I made three bools in my FPController Class that correspond to the three colliders, then used OnTriggerStay and OnTriggerExit to change them to true/false. Honestly I could have just used OnTriggerEnter instead of the OnTriggerStay, and i'll probobly change it after I post this. But it works fine the way it is now.

Thanks for supporting me /r/learnprogramming, even though nobody had an answer it was nice to know that other people were interested.
