Do you have a backup of your data?
Your volume is very full. You shouldn't fill it that much.
If you don't have a backup you may wish to consider contacting support and to enquire about the costs involved with a data recovery attempt.

If you need a data recovery attempt you should follow my advice in my post above and not try to fix it yourself.
