Labs to get for hormonal imbalance?

I've inexplicably gained 15 pounds in three months, despite eating very well and running six miles six days a week. I also have anxiety/anxiousness, very excessive sweating, dry skin despite three liters of water a day, extreme bloating and constipation, and jawline acne (I'm 34, female). I'm going to my GP next week and would like to know what tests to ask for aside from thyroid (which usually comes back normal), adrenals and DHEA. Thoughts?
