Can someone plz explain this query?

Hi, I am new to being on benefits and have little experience with living on my own having been in a relationship for 16 years and working as a HGV driver and also a combat veteran, then suddenly finding myself being made redundant and single in a one bedroom flat. I knew nothing of paying bills or of how the government works with regards to benefits as my other half used to do all that, my role was to earn the money, in which I excelled. Ha.
I was made redundant in June of this year…after being diagnosed with an illness associated with my previous life as a front line combat soldier. I lost my driving licence, so I could not carry on doing the job I have done for the last 21 years! Which led me down a spiralling path of being jobless, useless and eventually single and suicidal. ( you know it’s ironic, I was doing ok until THEY decided I wasn’t, which in turn made me jobless, and then that affected me more than anything)

Anyway I digress, the reason I am posting this is because I was asked to fill a form in. And then they said I limited availability for work and related activity…so I done the old Google and this led me to THIS site and is why I registered because I hear that I will be awarded ‘back pay’ now don’t get me wrong, I don’t want anything for nothing and I’ve never had any handouts of no one all my life…but when I lost my job and got this property I didn’t receive housing benefit fora while and I’m in arrears of £1340 and am being threatened with eviction!!
Now as u can imagine my mental health is already rocky and now I can’t sleep at night with worry…I’m thinking of doing bank robberies (joke…!) no but seriously I am sick with worry about this. I’ve never owed anyone anything in my whole life, I’m 46 yrs old ffs. So I messaged my ‘journal’ and this is what they said.
