Hi i'm a 35 year old female, i dont know if it is vertigo that i have but when i am walking across bridges with flow of traffic underneath i start to panic, can't breathe properly, i feel as if i'm swaying and can't walk straight, it wouldn't be too much of a problem but i walk to a certain destination with my daughter who is 6 and i feel so out of control when crossing these types of bridges, can you advise what i can do please.
