The Last Two Weeks Its Been Really Hot. I Thought

the last two weeks its been really hot. I thought I was dehydrated but all I drink is water, my vitals are great no infections. if I get in the heat I feel like I cant breath then I get dizzy sometimes I feel faint then that all leads to me panicking out dry throat. I quit smoking two weeks ago when symptoms started.only thing that helps is making myself freezing shaking cold.
