I passed my test 5 years ago, after several years of on and on lessons. Dual carriage ways no problem, went happily at 70 miles an hour whilst a learner driver. Went for PassPlus after passing my test so went on motorway with instructor.
Now find myself unable to drive faster than 40 miles, with or without children, scared stiff of dualcarriage ways, experience vertigo agraphobia, not quite being able to judge distances etc. On bridges, feel I'm going to drive off into rivers, gullies, drawn inexorably to dividing line on dualcarriage ways (whatever it's called), don't dare look in rear mirror in case I swerve.
No problems at all driving on normal London roads, in traffic, road rage, or doing runaround, in fact find driving in these conditions enjoyable.
Experiencing vertigo elsewhere galleries, treetop walkways, unrailed steps. Did not as a child or young adult.
Taking no meds for anything nor have ever.
