Migration grom IR ESA to UC

My migration was done back in July, it was a 3 month nightmare & when I thought it was finally over in July I recieved a letter saying I was now recieving New Style ESA & would have to attend a claimant commitment & would recieve a call. All my assessments etc have always been home visits or calls. But I was more shocked that I had been recueving cont based esa & ir esa. So since July I recieve £281.10 every 2 wks & a monthly UC payment with £609.05 deducted. So I stupidly thought all this migration thing was finished, wrong! Out of the blue this morn 3 months after recueving the letter I had a call from the job centre, straight away panic anxiety...I was told I need to do a claimant commitment call over the phone. I explained I have a support worker who helps me, as I panic with questions stumble if I'm put on the spot. So this lady from job centre who was very nice said not to worry & booked me for 28th Oct 10.15/10.30am. I asked what I would be asked & she said name NI number DOB, I asked how long call would take, she said 20/30 mins. It defo will not take that long to answer those questions, so what else will I be asked? The migration a 3 month hell with calls forms & eventually a DWP home visit. I had 2 support workers & my MP involved as it was such a mess & when think finally its done, this happens.

Both my support workers are busy, but my husband will be here, but ges undergoing treatment for cancer & hasnt been very well, so I dont to stress him.

I have felt sick day taken 15 mils of diazepam & still cant relax.

Can anyone advise what will happen over the phone? I did tell the lady from the job centre I was in the support group & she said she already knew.
