Telling family about NPD

I'm a mid-thirties male and I'm about to get fired from the third job in as many years. I'm a software engineer and just can't concentrate enough to do the job. I've also never really had a girlfriend or relationship with a woman.

My family is wondering what's wrong with me and if they ask I don't really have any good answers. The correct answer is of course that I have NPD. I'm not really opposed to telling them but I also feel a bit uneasy about it. Does anyone have advice or experience with telling family that they have NPD?

My mum cried but it cleared up the reasoning of me being "evil".

NPD isn't an excuse.

how come you never had a relationship?
you are supposed go through many idealization-discard phase ? :/
i'd choose better excuse than npd

I am in the same boat. I have a good relationship with my parents now, but did things when I was younger that I have never come clean on, although they had suspected or had no doubt I did them at the time. They think I am perfectly normal now. I have never had a problem holding down a job, and I am also married, but she was my first and only long term relationship which took me until the age of 35 to get there. Before that everyone did wonder what was wrong with me that I never had a girlfriend. Although now the marriage is not going to well at the moment because of my NPD which led me to hide frivalous spending habits from her which she has now discovered. I have now had enough of myself being this way and am coming clean about everything. To my parents, they know I've got a good job and I'm married, so they think my life is going great. However I need to tell them about my NPD even though I know it will bring up bad memories of things I had done in the past and also give my mother something new to worry about (she has OCD, anxiety, and slight case of tourettes).

I don't know about you but there is definitely some self-loathing and hating going on internally with myself at the moment, but I am also focusing on how good it may feel to finally fully admit my condition, come clean on all my past, and change. I feel like the saying "admitting you have a problem is half the battle" does apply here. Even though I feel embarassed and ashamed about admitting I have a problem to everyone who is close to me, it helps to put them on notice to keep an eye out for when I might be possibly doing something NPD and call me on it.

Imagine a future day how good it may feel to have faced your problems head-on and at least conquered some if not all of them. Even when I am doing something NPD, a small part of me feels the guilt of what I am doing. Therefore I know this small part that feels guilt can grow into a large part of me which feels proud of doing what I know is right.

Tell your family. If they truly love and care about you they will understand and do what they can to help you through it.

Thanks for the replies. To answer the question of why I've never been in a relationship, it's a long story. However, if you've been reading up on James Holmes and what his personality was like, you will have a some idea of my difficulties with relationships. He and I are very similar.
