Fixed term PIP ending. Told to reapply

Please can someone tell me what the average waiting times are, for a MR?

Thank you.

I have recently had my MR and I recieved a call from the Decision Maker, asking me if there's been any changes since my assessment, and to confirm my current treatments and medication. Obviously, I am deeply suspicious of any contact from them. I am now worrying and waiting for the decision letter.

I am now worried that the phone call will go against me.
