help = migration from irESA HB to

Hello - i am new here and couldn't navigate to finding any answers to my concerns. I am a long term recipient of irESA (8 years) in the support group and additional severe disability entitlement. I have a brain disorder, manic depression and acute anxiety. Earlier on in the year i received a back payment from PIP due to a change in the law regarding one of the descriptors within the PIP claim, it was regarding the need to pre plan mentally for travel that is not familiar, a journey or something that without mental preparation could cause you to become distressed. It wasn't something I was aware of, but I got a call from PIP and the woman explained I was owed a back payment. My concern is that when the migration takes place (have no idea when that will be either) and the UC need to see bank statements etc - will they see the back payment and deem me not eligible for UC? The back payment was not something I sought after or initiated. When I expressed my concerns to the woman she stated that I did not need to worry and at no point would the money be requested back and it was mine to do what I wished. It's not over the £16,000 savings threshold , so am i needlessly worrying here? Why do they have to take into account all of your finances again when they already have this information with ESA. ? Thanks in advance for anyone who can provide me with some peace of mind because currently i am so dreadfully concerned. Ideally i'd love to be able to go back into full time employment but the nature of my disorder prevents me from being able to offer the basic requirements of any given role, not only that I have had years and years of so many jobs prior to me claiming. All of which ended due to either being managed out of the company, once they were aware of my mental health. Had to go to tribunals and ultimately won - but not without a great cost to my mental health. No employer can account for EUPD, constant mood changes, impulsivity, let alone all the side effects caused by my medication. It's a very complex disorder. So anyone else in a similar position who has more info - that would be so greatly appreciated. uc
