Looking for advice as I am stressed and have had brain fog / mental block trying to start my work capability form.
In short I am asking what people think of my chances of getting in LWRCA as I am mothers carer and get PIp for mobility and daily living.
I have hip arthritis fibromyalgia L4/L5 disc herniation with canal stenosis, depression. Allodinaya pain and excessive sweating..Plus Childhood trauma to deal wit which comes.out recently due to urine and bowel problems. Oh forgot diabetes type 2 as well.
Been let down by Dr reports in the past I avoid going out due to anxiety re sweating and mobility problems. I have gone into my shell and refused a 3rd pain clinic and in the past refused to go to hospital to speak with crisis team. Not because I'm coping but because the stress of someone seeing me struggling to walk and sweating like a pig brings back trauma re as a kid I was severely punished for peeing the bed.
I have a phonecall wit my Dr Thursday and don't no what to say. I had a melt down looking at how bad my life is and I'm had to let stuff out so I just started emailing Dr practise to pass on emails re the trauma.
This work capability form is opening old wounds that I have kept under wraps for years.
I'm a mess and I managed to do Pip form but this I'm just struggling.
Sorry for waffle but just needed to vent. Any advice much appreciated
