Not sure what HVAC I want

I feel as if I am getting frostbite.

I have always had a personality that goes from one extreme to another! I will get super strict about my diet, for example, & begin visiting the gym exercising many times a week… Then something will shift, I can’t say how or why. It might be many weeks, it might be several months, that I will go the other extreme, stop working out altogether, & start eating like a cow. This is true in basically every aspect of my life, so it might be a mental issue I guess.Recently my shifting between extremes has been triggered by my temperature control system of all things. It is totally ruining my home life. I am finding it impossible to find just the right balance between heating & cooling. When the cooling system is on, that cool air blowing across my pale skin feels literally like a sheet of ice. I feel as if I am getting frostbite. When I turn it off, I instantaneously start heating up & within a few minutes and I am soaked in sweat. I don’t mean that I switch on the gas furnace, I mean just the absence of A/C is making me overheat. So what am I supposed to do, turn on the A/C & freeze, or leave it off & slowly roast to death like a Thanksgiving turkey? I have been playing around with some variations, & I think maybe if I switch off the cooling however keep the fans of the Heating and A/C system running, that might make me comfortable.
