All good questions...the first time I went into the hospital...my pdoc called the hospital to reserve a space for me...anyway he described me as high functioning when talking with them...that has always stuck with me...

Seems to me that you may also be high functioning in spite of other issues that really only a professional can say for sure...

I've been extremely successful in my work...even though everything else around me is well a mess...

It wasn't until the last three - four months that it started to mess with work...I took two weeks for a vacation...I think it helped...somewhat trying to get back into the swing of things.
