I can’t be the only one right? Specifically, I notice it happen when I play fps video games. I’ll literally be shaking and shivering while trying to speak with teammates and shoot. I always have to wear a heavy jacket when I play. Also, its like ~75 degrees F where I live, so it isn’t cold here.

Your body is resorting to a very old protection scheme. We have evolved to prevent blood loss by restricting blood flow to the skin. We come from a long line of animals that had evolved ways of protecting themselves when injured. Those animals that did not have such protection died when injured, and took their genes with them.
When you get hyped up playing a game, your medulla oblongata ( part of your brain stem ) interprets your excitement as a response to danger, and prepares your body for battle. It restricts blood flow to the skin so when a leopard rips open your leg, you don’t bleed out. ( FWIW, it also tells the adrenal glands to release adrenaline. )
With less blood bringing heat to your skin, it feels cold.
