ESA help

In July 2015 I had to leave work due to having serious anxiety and depression I was stated unfit for work by my GP and started therapy to help me deal with my problem. I was put on various medication while i received ESA round about November 2015 I had a medical assessment which I received 0 points and my payments stopped.I appealled against the decision and I got to go to court in the February 2016 with the help of my local CAB,welfare rights and supporting letters from my GP, I'm happy to say I won my case and was awarded WRAG and a 24 month to be reassessed so it gave a bit breathing space to help with my therapy and I was backdated the amount I was entitled to.
I carried on with the help from my GP and therapist until July 2016 and I did feel lot better in myself with my confidence etc and a local job came up in my town which I had to try and go for as I have a family to support with our own house, so I got the job and signed off ESA within 4 weeks of working I was back to square 1 even worse to be honest with terrible social anxiety and I had to make the decision and leave as I could not take the torment I was faced with so I had to reinstate my previous claim of ESA as it was within 12 week period, so I started to get the normal payments of ESA and WRAG I was getting before until December 20th 2016 and it was stopped yet again after another medical assessment I had to go for after been on ESA for X number of weeks,which I thought my 24 month awarded by the judge at court would just follow on for WRAG well this time I was awarded 6 points at my medical not enough eventhough I'm trying my upmost best to get back to work.and I had a lot of evidence from gp.
So I'm back where I started its like deja vous so I appealed against the decision again and they accepted and am getting temporary ESA without the WRAG payment eventhough I was awarded this for 24 month until I get my date for the actual hearing it is now October and still haven't received the brown letter.
Since July 2016 I have been working with talking changes with the different stages of therapy which was available to me and am now on the final stages of the more intensive sessions EMDR which has been very helpful to me eventhough I have all this nightmare to deal with ESA and am now working with a work coach to get back into work as I have learned a lot how to deal with my problems I've had in the past.
What I would like to know is if I did get offered employment before I get the date for my tribunal would I lose my backdated entitlement for the WRAG I was awarded if I sign off ESA and go back to work because all I have been is honest and this has been a journey what I have put in to get where I am now and don't want this to make me go back to where I was before, all I want is to get back to work to support my family.
