Hi lph! I think the Anti TPO results means you might have an autoimmune condition, like Hashimoto's. I don't know whether your doctor would want to medicate you with your normal range tsh, but you should ask if that's an option since you're having some classic symptoms.
Keep an eye on your eyebrows. An early sign that things aren't right is thinning at the outer edges.
I hope this helps a little! I've been on levothyroxine for a few years now and it's made a huge difference. I look at pictures of me from right before I was diagnosed and I look years older than now.
