A bit lost

I have been dealing with aspergers for most of my life, undiagnosed (came close 8 years ago, but an unhelpful medical professional tore up my assessment documentation and told me there is no such thing and I am a perfectly fine young man; after reflection over many years this was a mistake).

I have reached a piont were I do not know what to do.

I have angled my life so I can work from home. My wife understands me very well and is supportive. 

But, it is becoming a struggle to maintain appearances to my clients.  I am severely literal, and find it exhausting to understand the subtext and pleasantries in business interaction.

Any advice, and coping stratigies would be welcome.

Most recent incident was a joke said by an absent minded support staff-worker, which cause quite a costly mistake in a recent event. This type of thing cannot continue.

Please help.
