Hi Julksy,
It's nice to catch up with you again, hope you're well!
I have the same answers as Dutchy for those clues.
6D. Neurotic = Maladjusted
adapted = adjusted
'Mal'+ 'adjusted'
80A. Spite = Nastiness
awful 'stain' = nasti (letters rearranged)
Scottish lake = Ness
44D. Cutting off = Disconnection
relationship = connection
'Di's' + 'connection'
Good luck in the competition Julksy, hope to talk to you again soon.
Take care, warm regards Butterfly
