A common stigma in Mental Health is that sufferers are Chronic Liars, a very offensive misconception.

It doesn’t take a lot of effort for educated people to discern that the mentally ill can’t lie.
Their ‘Distorted Reality’ is Shame, a desperate attempt at Protection.

The Neurotypical should be supportive towards Shame, rather than accusatory.
Still a long way to go.

The bad news is that Shame evolves with time. 
The last stage is Isolation.
Although it is never too late to reach-out, the more opportunities are lost both professionally and relationally.

I would also suggest sufferers to take action by self-educating.
I said multiple times that Masking is a short-lived failing technique.
You have nothing to lose by disclosing your mistakes asap. Even the toughest boss will be more sympathetic in the short run than in constantly hiding.
Easy said than done.

There are techniques to gather courage.

You’ll notice that I refrain from using the word “Lie” by referring to synonyms like Shame, Hiding, Protection, Mistakes, Masking, Disclosures, Timing… these unproductive Behaviors are not malicious Lies, despite perceived as such by most Neurotypical.

Buying Time is vicious and exacerbating.
Drop the Mask immediately.
Just think that the more you wait, the worse the consequences.

You have only to benefit from Honesty.
Honesty is always valued. It comes with Humility and Commitment, particularly in the workforce. 

Layoff is possible, although to your Wellness, typically good referenced for a more specific position supported by your employer, in this instance. 
It meant that job was detrimental to you and other more suitable doors will open.
It happened to me, with my Supervisor addressing me to my current satisfactory job directly and a warm shake-hand.
Job-centers have Disability departments offering Job-seeker s Allowances.

DON’T PANICK.

You’re never a failure as long as you try.
You know what medication works best for your disinhibitions, talk to your psychiatrist into adding a extra pill just to abate Shame for that new job-interview.
You’re not alone. You can do it.

And may God s love be with you
