I am extremely fatigued and had an episode where I was unresponsive. Please help.

Hi doctor,

I have hypothyroidism, Hashimoto's disease, high blood pressure, and type 2 diabetes. I was diagnosed with microcytosis before few months. I also have fibromyalgia. I am extremely fatigued and I feel very weak. I am unable to tolerate the sun because I start to have rashes on my skin. They cause itching and burning. I have a lot of pain in my joints. My hands have turned red and my middle finger has become white. I have had profuse sweating for the past two months. I am not able to sleep well. I have a pin and needle sensation all over my body including my face and head. It feels like someone is poking me with needles. It burns and itches a lot. Two months back, I was talking to my brother and I sat on a floor propped against the bed. My brother told me that I was talking gibberish and started to fall to the side. He told me that he has caught me and I was unresponsive at that time. I do not remember anything. I got tested for lupus before four years. I always have health issues. I am taking Levothyroxine 137.5 mcg, Lisinopril 40 mg, Metformin XR 500 mg twice daily, and Iron tablets.
