Hi m4 and welcome to the forum
Well firstly you should have advised your IP of your change in circumstances when this happened, and you must now tell them as they obviously do not even know your current address.
It is possible for you to ask for a payment holiday - I suggest 6 months - to enable you to sort matters out, but this can only be done by your IP calling a creditors meeting and explaining the circumstances. The creditors will then vote to either accept or reject your revised proposals. For this, you will need to co-operation of your Supervisor, so please now take immediate steps to advise him/her of what is going on.
It does seem that you could do with an all round change of residence/job, so why not give things a go and see what transpires over the next few months. If all else fails, bankruptcy proceedings are also an option for you, given that you have no assets.
Hope things work out for you - and do remember your future is more important than worrying about the IVA payments for the moment.
