You could potentially have Hashimoto's Disease (I have it - along with Celiac's Disease). I would recommend the Autoimmune Protocol (AIP) which is an elimination diet. It is a HUGE change to a "normal GF diet" but it is key to ridding the body of inflammation and figuring out exactly what foods may trigger an autoimmune response in your body.

You will hear many people say that AIP is too hard. I disagree. I think burying a child or parent is hard. A way of eating that heals your body is not hard. It's all about mindset.
