To be honest 4 years ago I had to have some time off work, it just got to much. I hit the bottle and the GP signed me off recommended i seek help, i didn't i just got myself better. I said no to the mental health question so in effect I lied as it was mental health issue, when i spoke to the doctor he brought it up . I wouldn't sweat it at all you'll fly it.. as for the email yeah DVLA wanting more info they just emailed instead of posting to gp.. I've been a constant pain for my the delay and gp past few months ringing all the time for updates but seems it's the only way to get forward
