For years i've had hands and feet that sweat very easily, even if i'm cold. could this be too much sugar making my body damp?

Hyperhidrosis: Is it the palms and soles that sweat? It sounds like you have palmoplantar hyperhidrosis, which is fairly common and unrelated to sugar metabolism. Try applying a product such as certain dri to the palms and soles every night. There are also prescription strength antiperspirants, and procedures such as tap water iontophoresis or oral medications. A dermatologist can help you.
