Pro-tip, dehumidifiers work great, but they blast hot air back into the space they’re in. Air conditioners do the same job, they remove humidity from the air, but they are designed to vent the hot air/condensation out of the living space. So they lower both humidity and temperature. A portable or window AC unit will cost about the same as a dehumidifier.

I found that attention to which fabrics I wear and which I use for bedding helps a bit.

The options for clothes include light breathable "tech" fabrics (usually polyester in a trenchcoat - with a special weave or blend - unless you get into the expensive end of the spectrum), light wool, rayon (viscose, lyocell/tencel, "bamboo"), and linen if you can stand the texture.

For bedding, rayon if you can find it and linen.

The secret with wool, rayon, and linen is that they can absorb/contain vastly more water before they feel damp to the touch!

I hate heat so much. i feel like im dying in heat do to not sweating correctly. im type 1 diabetic and im pretty sure it fucks up how i sweat. i get soaked and it is so gross.

Yeah, the north east of England rarely goes below 70% humidity. The winters aren't too bad: the cold sticks to you, but you can always fix that. The summers, though, are very uncomfortable for me.
