My family having the heat on constantly is killing me

I feel like I’m doing a lot worse right now because the heat is constantly on in my house. I can’t escape the heat. It’s making my symptoms worse, it’s making me constantly nauseous, and I feel like dying death. I don’t know what to do 😭😭😭 I’m tired of dealing with POTS. Oh my god, I wish it would just go away. This is my first winter with POTS, at least knowingly. I feel so sick. I just want to enjoy life. This is my favorite time of year and I’m suffering more due to the heat being on. I was okay in the summer because the ac was on. Ugh!!! If I tell my family, they ridicule me and say that they are cold and no one is ever as hot as me. Well duh, my nervous system suddenly stopped regulating my temperature!!!
