If I go to an allergist for fatigue and itchy scalp/eyes/ears will they laugh at me?

I'm at the end of my rope with trying to figure out why I'm always so exhausted. I eat extremely healthfully, sleep well, hydrate well, exercise regularly, take all the recommended supplements. But I'm always so depleted and fatigued. My scalp and inner ears are burning and itching all the time now. My eyes also feel like they're burning. They look totally normal but it FEELS like I have lice and some times of infection in my ear. I have seen doctors for this and they tell me it all looks totally fine. Except my eyes - the eye doctor did give me steroid drops for inflammation that he saw. I do have seasonal allergies and I have extreme reactions to bug bites. I occasionally get hives/rashes but not frequently.

I'm worried if I show up to an allergist and say I'm tired and my head/ears itch they won't take me seriously? Does this sound like it could be MCAS to you all and does it seem like something the doctors would be able to help?
