Best of luck with your migraines! I had a high thyroid number too until a forgettable number of months ago, and it was fairly simple to sort out with an endocrinologist. She even told me it would help tremendously with migraines, energy and such. (Other conditions got in the way, but hey! Maybe it's just what you need!) I'm sure you've already heard this, but don't let anyone downplay anything! Exaggerate, if that's what it takes to be taken seriously. That was rather hard when I was a teenager. Don't let anyone tell you that you're too young.👍

Oh yes, It’s really hard to be heard simply for my age. Everyone is also limited for adults, not even teens can reach out to others with their conditions simply for their age and it’s such a bothersome!

I've had migraines since high school and no one believed me! Mine are from other causes and still affecting me at 26 but just wanted to let you know I've been through the same thing due to age. You're not alone, I found 1 doctor in my teenage years that actually listened and attempted to help but had no idea the cause of them so it didn't help at all lol. The support was nice though.
