What to do if i have a spot on the white part of my eyeball (unsure of the name for the white part of the eye) cont. below?

Pinguecula: Sounds like a pinguecula, which is a deposit/build up on the white part of the eye (sclera) due to uv light and dryness of the eyes. You can use artificial tears, and use a cap and/or sunglasses when outdoors. Sometimes you do not notice them until there is inflammation causing a red background making the white spot(s) more noticeable.
