Sorry to hear this pal. Just to echo what everyone else has said I would hold fire on selling the 8.
I was in this situation years ago and hastily sold my car and regretted it. Things worked ok in the end as I found another job. In hindsight i also realised I had enough in the bank to keep ticking over whilst tightening the belt a little.
Fingers crossed it all works out
