hi mitch,please dont despair,your ip will adjourn your creditors meeting to try and persuede creditors that they have put your best propoal forward,and try and find a way that your creditors may except your iva,creditors will often come back with modifications that you really need to give serious thought to,but until you hear back from your ip,i would just wait,its not unusual to adjourn a creditors meetings.
I think you should think about alternatives only if you do get rejected,you have enough worry at the moment,i really do hope you get a good result,im no expert,im sure you will get advise and support,goodluck
