Should I See A Doctor For Excessive Sweating, Heat Intolerance, Hair Thinning, Hand Tremors, And Irritability?

I m famous for hypochondria in my family and friends. So I don t ask for any medical advice. Just a piece of advice about should I even go to the doctor. I m 19. Earlier I was always cold. For the past few years, I m always hot. Sweating buckets. Sometimes it even drips down my arm. I can t stand the heat. My hair is brittle up to the ears point. It also got way thinner than before. My resting heart rate is 84-88. I m fairly active. When I put a piece of paper over my hands it trembles. I m nervous and easily irritated. On the other hand, my weight is stable. And I don t see any bump. So should I visit the professional?
