Problem: weird laggy walking in one direction

Okay so the up arrow and left arrow are messed up somehow in my controller. When I walk forward it goes diagonally left VERY slowly. My speed is set to 6. What is the problem? Walking backwards and right is fine! This is my first day coding with Unity btw. I am currently trying to assign Animations to the character. Right now the Idle animation works but nothing else.
It’s like my feet are stuck in the ground! (I made sure the wireframe was above ground before posting this)

I looked it up on youtube and after strenuous searching found my answer. The character was simply inside the ground and only allowed to go in one direction very slowly. I have now made the practice of putting the character 6 digital feet off the ground.
