PIP Mandatory reassessment

Just as I expected,  my PIP Mandatory reassessment gave me zero points just as the original assessment. 

When applying for PIP I got expert help and advice.  And the people who suggested I apply for it, actually filled my forms in.

So I'm stuck between the cracks and falling in.

Employers have fired me for being unpredictable,  having bizzare behaviour,  untrusted to work alone and unable to work as part of a team.  And my physical health and insomnia has lead to disaplinary action being taken against me.

DWP and their sister organisations insist that I am in perfect health both physically and mentally. 

What do I do now?  Apart from whinging and whining on this forum?
