Suffering From Hypothyroid, Severe Eczema. History Of Depression. Which Specialist Should I Consult?

Question : I have chronic, severe eczema that became much worse in menopause. Also, I'm hypothyroid. Long history of depression. recently stopped welbutrin. it was creating harmful sideeffects. Light treatments, corticosteroids weren't helping. It's been 1.5 years of out of control eczema with a new development 3 months ago, a burning sensation on my back or chest, depending. Red rashes without pustules for the most part, on my face, neck, arms. I'm very careful about allergens, on gluten-free diet. Use aquaphor constantly. exercise is limited to swimming in salt water(not often). Have a high stress life. rashes can come anywhere, swiftly, now I have violent reactions to many things. a skin biopsy was positive only for atopic dermatitis. I work in a corporate environment with central air/heat. eczema worse when winter heat goes on.
I don't know whether I should be consulting a dermatologist, an allergist, an endocrinologist, or some other specialty.

I am hoping to deal with the underlying cause rather than take an immunosuppressant. Is there any realistic alternative to the immunosuppressant? Any more natural way to deal with this?
