Open Question: Moving to North Carolina, Looking for Health Insurance?

I've decided to move to North Carolina when I save up enough money to do so, but I realized Health Insurance is also something needed when moving to another state. So I decided to look up quotes for Health Insurance in North Carolina so I could figure out how much money I should save up before moving. It all looked good and fine at first, but I realized some insurances do not cover pre-existing conditions, I have a hypothyroid, so I need monthly medication. Also a lot of online insurance information gets very confusing, one minute it covers something and the next minute it doesn't. So is there some way I could find an affordable insurance that will cover my needs, while staying in Massachusetts so I know how much I need to save up in order to move? And is there someone I could consult about it? Like someone who gives free or affordable advice on which health insurance is the most affordable and gives the best benefits? Or maybe someone who has had experience with North Carolina insurances and knows which plans are affordable and provide needs including pre-existing conditions?
