Chat how tf does one fight? 😭😭

I'm not gonna lie I'm like the 1st opponent in og punch out 😭. But I've got a fight set for Monday morning against my gf's assaulter (he also called me a 'cut slut' knowing my MH history so yk). The whole school knows and I've been practicing my punches and movement all week, yet I'm probably gonna make a mockery of myself. Please help bruh 😭.
