I am so sorry for you! Sounds like classic IMS failure.
Not to pour salt into the wound, but the mid-generation 986s and 987s are more prone to this failure than the early cars due to a redesign of the intermediate shaft.
You can now look to a 3.4L or 3.6L replacement. There's also a company in the UK which has a permanent fix to the problem and this may also be an option being a commonwealth country and all. See:
