Pip early yeR review

Please I need help my last pip award was till November this year but pip has decided to review a year early even tho I ever reported any change in fact my health has really detoriated since than as I can no longer go out my front door I suffer with bipolar and restless legs trapped nerve in my neck anxiety and panic attacks severely I couldn’t even go to my own daughters wedding last year I committed suicide but my son found me who was suppose to be at work and feel terribly guilty about that but what my question is they have reviewed it and came to a decision where I have lost my enchaned rate of care and my standard rate mobility so my money has gone down considerable six months before my last ward was too so in my eyes they have saved there selves £3000 + in payments for 6 months because they have reviewed early and I have lost that money to live on and just don’t know how I can cope I have asked for MR which can take 10 weeks and by reading people’s Post it’s an likely anything will change and I will have to fight to court for it to be look at indepently which is scaring the life out of me I have a very stressful life with my 3 children’s unhappy relationships sometimes to the extreme of police being called to my address I have never lived like this my life has always been respectful any way sorry for the rant but my real reason is can the pip change your award to the lower rate even tho your last award was given till November I’m at my wits end I person tells no next yes but when I speak to pip they say there is nothing they can do and the new award stand as from now and will need to go to appeal but either way they will not reinstate the next 6 months rate I’ve lost. Please if anyone can help me on this I will be so grateful even if it is bad news I just need to know what the right thing is as so many conflicting information x
