Sorry to hear you are poorly. In addition to the questions above - how long do you have left running on your IVA? Do you have anyone who can help you liaise with your IP?
If you are receiving support via a CPN etc. make sure you mention this as they may be able to point you in the right direction for support.
Also speak to the CAB.
If your mental health issues are documented make it clear to the iva company what they are especially if your capacity to consent is variable.
Unfortunately there is an element to all this where you have to find the strength to work this through unless your issues are so severe that someone else has lasting power of attorney for you.
IVA started March 2011, Completed March 2016 and certificate issued 11 days after final payment. It was not always easy but then some of the best decisions aren't.
