Handfighting

I’ve been wrestling a few years and I’m varsity. I have a pretty good defense and a good system from my headlock. A good reshot/shot too but my big problem is hand-fighting. I only know how to take shots from space which I’m realizing recently is a problem because every-time I end up in a hand fight situation I lose to most people. Any tips? Or any wrestlers I should watch? Thank you very much.
