I Am Only 41, And Get Dizzy When Outside And

I am only 41, and get Dizzy when outside and look up, even if lying on my back flat but not inside and it is almost nauseating. Then when crossing bridges that have and incline I must put my visor down in tha car so I stair at the road and do not see the incline and do not look up because I will get even more dizzy. If the bridge has suspension or towers I can't look at theme I get dizzy and panic, if I get to panic state I see stars, feel faint, sweaty pans that can barely grasp the steering wheel and my foot can barely push the excellerator and I slow down when I would rather speed up and get it over with... This is not vertigo since I ah e done the exercises and do not get dizzy any other times then outside trying to enjoy a great sky view or the incline on bridges etc..
