I have the roid depression and anxiety cholesterol and i would like to know what happens is i don't take my cholesterol pill cuz it gives me headache?

Cholesterol stays up: When you don't take your cholesterol lowering medication nothing happens except your cholesterol isn't lowered. You would not have any symptoms. However, I doubt the cholesterol pills are causing headache; more likely result of anxiety or thyroid situation. Usually, we don't like to use cholesterol lowering medications in young women like you anyway. Low fat/high fiber diet & exercise is best!
