Handhold from me, OP
Back in 2010, I was in a bad state of depression. My house was similar to what you are describing. My CPN was out with me one morning and a mouse ran across her foot. She wanted me sectioned as I was in a severe state of self-neglect. Food was off but I still ate it, I didn't care, She then went from living room to bathroom and that's when she saw the extent of my hoarding and the state my house was in as well as me. The bath was full of stuff, as was the shower. The hallway to the front bedroom was blocked off by about a meter depth of stuff. The bedroom turned out to have rats. The other rooms were under siege as well. Things were dire. She got the GP to visit with a view to getting me admitted to hospital.
Thankfully the GP was sensible and suggested what I had been arguing with CPN that nothing was going to happen with it if I was on the ward 30 miles away and it would be the same when I got back and would be as overwhelming as ever. I was in physical pain but the cause wasn't diagnosed at that point.
GP upped the painkillers that I was on. Called a team meeting and a social work assistant was allocated to help me sort things out. I had intervention from the home treatment team to support my mental health. The SWA handed me a small cardboard box re the front bedroom with this was what I had to my most important stuff into. The industrial cleaners were coming in. I was given a small box for my bedroom and another for toiletries. She went thru everything in the kitchen with me, packing all utensils up and pots/pans etc and they were taken away temporarily to go thru wash cycles. All the clothes that sat around the place, some going mouldy as couldn't dry properly, were sorted as she worked with me. A lot was dumped as unsavable and the rest were bagged up and sent to launderette for industrial washing..
This all kicked off on a Monday and by Thursday 2 pm I was done all I could do, a lot of stuff had to be skipped. Things needed dumping. The stuff the landlord had never got around to repairing he was contacted and given a list and a date to come in and fix it.
It was arranged I would go to the "assessment flat" in local supporting housing as a temporary measure while my home was made habitable again. I was there for 3 weeks. In that time, the house was emptied and the stuff to the skip by the cleaners who apparently took it out in bin loads.
The pest control service then stepped in and they sorted out the rodent problems. They also got the landlord to deal with the mould problems.
While I was in sheltered housing my meds were adjusted as there was a twice weekly psychiatrist visit to the unit. So when I left I came home to an almost empty house, my friends had come in after pest control was done and gave it a clean and got food in.
I had the support of the SWA for 6 months to make sure I kept it under control. The CPN was allocated to visit weekly. The GP came to visit when I was home for a cup of tea and a look around. They knew how hard it was for me but knew I wanted to carry on living there. The landlord gave me hassle but he was a prat anyhow.
I was given a second chance. I had to pay for the pest control but the rest was funded from the MH budget. It cost me £300 for the pest control who visited twice a day and did their thing.
Before the SWA signed me off she referred me to a local floating support housing workers, who I have been linked it with at various times. They come and encourage sorting stuff, we do it together, have a laugh and most importantly they take stuff away asap out of the house so I can't change my mind. Its the support is the best.
They have made me feel like I'm worth it again and I can contact them anytime. I tend to sign up for 2/3 months at a time to get the support to declutter and reorganise and then I sign off.
You deserve a lovely home too. It's hard reaching out for help, it feels shameful to let people see the way things are. I had no choice as it was either that or hospital admission and admission wouldn't have solved any problem. It took practical help and encouragement and also getting away from it while some bits were done. I was 20 miles away from the house and so couldn't come and halt it easily while I was away.
So think about talking to your GP / CPN / SW as this is impacting on your mental health and you deserve help.
When I tried to do a clean myself it was usually the emergency cleaning from UFYH

Cheering you on from here and hope this gives you some hope, things can get better. Talk to GP first to see if can help pain, infections, mood and go from there. One small step at a time
