Some unsolicited advice couched as experience that may or may not help you:
I struggled with this off and on for years, and still do if I don't take some specific actions. They aren't a total fix but they help.
Turn off the air handling in your house and open it up at one point in the day, preferably a few hours opposite of the seasonal trend (early morning in the summer and early afternoon in the winter). During this time go take a decently long walk in appropriate clothes. When you come back close back up and set the thermostat to whatever the temperature cycled to.
This tends to work to shift seasons more naturally as well. If its hot outside it will feel cooler inside even if the temp went up a degree, and this compounds all season. The reverse is true in the fall/winter.
If I don't do this I struggle very similarly to you all year.
Maybe that can help you?
