Please Help.

Hi, In june this year i got married after being together for 25+ yrs & moved in with my now wife, id been on an esa work group for 20+yrs & was asked to go to a routine assesment in the July in which i notifed them of my change in maritial status, the outcome was a good one as i was moved into the support group which helped so much, after a few wks my money was not in my account & when i asked for the reason i was told it was because id not said about my change of addres & would need to fill out a form regarding my change in circumstances which asked about all my wifes incomings etc, my wife works part time only as she basically has to care for me, after wks passing without no money coming in for me & only my wifes wage & child support which is also far less than its meant to be according to the CAB, i finally receive a letter (5th Oct) from dwp saying im no longer getting ESA because of: A Change In Money Coming In. ????... My wife spoke to a CAB advisor who said that i should apply for PIP & so phoned & iv just now received the "How your disability affects you". Iv not yet called the ESA Dept questioning this letter/decision yet or to formally appeal(mandatory 1 mnth deadline) as im totally at a loss where to even start. Normal day to day living is hard enough for me to cope with due to my mental health aswel as phyisical mobility problems from having a DVT in both legs 10+yrs ago & having to be an out patient at the hospital Anticoagulant Clinic every 2-3 wks. Can anybody help Please.

Thank you Gordon for the prompt reply. Im sorry if i wrote my question in the wrong part of the forum, im not to great when it comes to finding my way around forums or most things on the Web & only managed to finally find the site after being told about it when someone heard about how much stress the situation is having on me.
Anyway, iv been on benefits most/all of my life due to mental health issues & then later in life had physical problems in my legs due to having a DVT in both legs resulting in long term treatment at the local hospital Anticoagulant Clinic.
I was always on Income Support before getting put onto ESA in a WRAG although i never once had to attend any appointments to do with being in a WRAG or any other appointment as my JC Advisor knew my mental health issues & problems i have interacting with people so would just phone me a couple times per yr !! Dont know why they had just only now been moved to the ESA Support Group after so many yrs come to think of it....
You asked what type of ESA i was receiving before it stopped & i can only manage to work out by the letters sent is that it says as well as "The change in money coming in" it also states as iv not payed enough or been credited with enough N.I Contributions, so i presume i was getting Income related ESA.
Also my wife works less than 24hrs per wk. Iv not had a payement since the 22nd Sept 2018 now & the stress of it all is unbearable, i even have to get someone to post on the forum for me as im unable.
Thank you for your time & very grateful for any help.

Hi,
You said that on a rough basis i should be getting £175 pw ESA (support group) and if my wife was earning more than that then its rather a black and white decision for me not to be getting it which i now understand thank you but was just wondering if this sounds right to you before i mandatory appeal their décision.
I was getting only £127.15 pw :
Living Expenses - £73.10
Extra money for Disability Income Guarantee - £16.40
Extra money for being in Support Group - £37.65
Total - £127.15 per week.
The amount i was getting seems a lot less than i expected aswel as what you roughly estimated i was receiving and also my wife does earn less than what i was receiving
