Allergy

Hello, I am from Turkey. I am 17 years old. For 3-4 years, when I get excited, when I'm stressed and when I move from a cold to a warm environment, my whole body itches when I walk in the cold. I used a lot of antihistamines, cortisol. Even though I used some drugs with special permission, there was no solution for my illness. I don't know if it's an allergy. I'm also not sure exactly but it is close to the start of winter and is happening much more often in winter. I mean, it's not cold urticaria, and I'm having a lot of it in the summer. I can't go out anymore, please help.
