How would you answer this question on a medical form?

While filling out a medical history questionnaire for “cutting edge” medical company, I was surprised to see these:

Suicide? Insanity? Nervous Breakdown?

I have a history of mental illness, as do members of my family, but how do I answer this? I tried to catch suicide once, but never actually got it. My psychiatrist hasn’t mentioned whether or not I am mentally ill enough to be insane or if my anxiety is at nervous breakdown level.

For now I have left Suicide blank, checked Nervous Breakdown and written “Really ?” beside Insanity. That’s going to get me off to a good start with the office staff.
