Help! It’s become an addiction

So I can’t not use it unless it’s the middle of summer. I’ve done this for years now and I think it’s staring to affect my skin.

So when I get in bed I’m usually cold because my husband and I can only sleep with it cold. I always have to fall asleep with it but not ALWAYS use it throughout the night. Just sometime. I keep my heating pad between my legs , from my knees to my ankles. I love heat. I take hot showers and hot baths. I don’t know how to stop 😩 I think this is what’s happening from it but I’m not 100% sure. It’s only on the part where the heating pad is. On the inside of my legs. No idea if it’s permanent or if I stop will it go away.
