Honoria Anonymous

Story

"Gentlemen!" spoke the young man at the head of the table, "My name is Bertie, and I... was engaged to Honoria Glossop."
"Hallo, Bertie!" chimed in the four other men at the table.
"Why don't we all introduce ourselves? My name is Biffy, and I was engaged to Honoria Glossop..."
"Hallo, Biffy!"
"My name is Percy, and I was engaged to Honoria Glossop..."
"Hallo, Percy!"
My name is Gussie, and I was engaged to Honoria Glossop..." "Hallo, Gussie!"
My name is Cedric, and I was engaged to Honoria Glossop..." "Hallo, Cedric!"

Thus began another meeting of Honoria Anonymous, a self-help group formed by the former fiancees of that brainy and imperious young woman. There had been slips in the past, but now the 5 men present had managed to remain uncommitted to Honoria for various lengths of time: 3, 4, 5, 6, and 7 months, (each member having been free of the influence for a different period). Today's topic of discussion was "Honoria's little gifts", each victim revealing a present received from Honoria with a view toward repairing some personal defect. She had given them, in turn, the Complete Works of Nietsche, a dozen extra-stiff collars, a Correspondence Course in Self-Hypnosis, a gramophone set of Wagnerian opera, and a Bed of Nails (acquired from a world renowned yogi).

Then one member delivered a paper entitled, "How Sir Roderick Glossop (bless his soul!) came to view me as Criminally Insane". This inspired a response from each gentleman, who fondly recalled that eminent looney doctor's summary of his own character: "Nervous Wreck", "Mentally Deranged", "Latent Psychopath", and "Bats in the Belfry" (a medical term, one supposes) being the terms that Glossop had applied to each beau, in breaking off the engagements.

Now, the members of Honoria Anonymous are sworn to secrecy, so they can only drop hints about what was revealed in their meeting.

Can you piece together, from these 8 clues, who has been Honoria-free for how long, what gift he received from her, and how Sir Roderick summed up his psychological diagnosis of each specimen?

Clues

1. The fellow Sir Roderick called a "Nervous Wreck" was set free one month before the fiancee who was treated to the Self Hypnosis course.
2. The "Latent Psycho" was not given the Wagnerian opera records.
3. Gussie (who was not dubbed a "Latent Psyschopath") did not receive the Stiff Collars.
4. Bertie was set loose two months before the one Sir Roderick found "Bats in the Belfry".
5. Percy was not found "Mentally Deranged".
6. Cedric and the chap who got stuck with the Stiff Collars are each celebrating an even number of months of non-engagement to Honoria.
7. Percy was set free one month earlier than the candidate who received the Bed of Nails to improve his self-discipline.
8. The young man whom Sir Roderick judged "Mentally Deranged" (who did not, by the way, receive a Self-Hypnosis course) has been free one month less than Bertie (who didn't gain his freedom exactly five months ago).
