Does anyone else just look very ill / sickly?

I do not have a diagnosis yet but I swear you can tell just by looking at me something is very wrong…. I am very pale, my hair is falling out, my skin has rashes, I look weak and tired.

I really don’t know what to do. My thyroid is fine, I’m not anemic, my vitamin D and vitamin B12 are all normal. I have severe fatigue/weakness, dizziness, nausea, body aches, heart palpitations, headaches, and insomnia. It is impacting my ability to function.

Could it be a GI issue? Should I push for more autoimmune testing? I am not sure on what else to ask my doctor for. Please help :/
