Hello I’m new and need help

Hi, I’m hoping someone can help me.
I was in receipt of incapacity benefit and was awarded it indefinitely then it changed to ESA and I was sent for a medical every 3 years and for the past 2 medicals I was placed in the support group but in September I received a phone call a couple of weeks after my medical saying my money had stopped as I received 0 points.
I very nearly lost my life to TB meningitis in nov 2000 and this left me with weakness down my left side, unsteady gait speech and memory difficulties and severe headaches which were later diagnosed as secondary BIH an incurable brain disease which causes me to have visual disturbances, horrible headaches, confusion, dizziness and tinnitus. I also have IBS with incontinence, liver dis function, carpol tunnel osteoarthritis of the left knee with bone spurs and 2 cysts and anxiety with panic attacks.
The doctor that assessed me has told lies on the report and it is this that is the most upsetting part I really can’t understand why a medical professional would tell such lies.
I requested a mandatory reconsidering and that was the same result so now I have appealed and I’m going to tribunal.
I don’t know what to do as my neurologist is unsupportive and my doctor has just retired so my new doctor barely knows me so I don’t know how I could ask him for a letter of support as he doesn’t know me.
I attend pain clinic, muscular skeletal but have recently been to see a mental health nurse and she wants me to go for some therapy and also has referred me to occupational therapy, incontinence clinic, memory clinic and has asked my doctor to ask pain clinic to reassess my treatment as I’m not coping well with pain.
My head is all over the place at the moment I can’t think straight and I don’t know what to get for evidence to submit to tribunal or how to obtain evidence.
My husband has wrote to our MP and he is very supportive he’s also wrote a letter of complaint to the DWP about the medical assessments lies.
I’m going to see the doctor on Monday as the DWP have message my husband asking for a sick note so we have to go and get one, should I ask my doctor for anything else whilst I’m there?
My husbands friend is a consultant cardiologist and he’s said he can write a supportive letter if we need one as he see’s me personally in my own home and he knows better than any of my doctors what I struggle with daily, would this be of any help?
Any advice on what to do will be greatly appreciated

Hi, I don’t know the reason for being placed in the support group previously. I’ll have a look through the information. Thank you

I would expect to score maximum points for moving around as I can’t walk 50m without stopping due to pain I also need my husband assistance to walk. I expect to score points on moving from one place to another as I can’t get up out of a chair on my own.
I also should get points for incontinence, speech and making myself understood and routine changes.
