My throat feels tight?

I've been having problems with my throat feeling tight, especially at night when im lying down. It doesn't hurt and doesn't effected my normal breathing or swallowing. Though when i put my hands around my neck very un-tightly (barely putting my hands around my neck) my vision become distorted and like im drunk but im not. though i have a history of making things seem worse then it seems but i'm stating exactly "exactly" as i feel. I know that my thyroid gland is in my neck and obviously i need my throat to breath and eat but im afraid of doctors and this should be probably something i should go to the doctors about but im too afraid.

Any help wll be appreciated
