Why can't I follow my own advice and my screaming guts?

I give advice for a living, amongst other things. Strangers come to me in a traumatic situation and I help them through it. All day, every day. Lots of them for a long time. I'm really good at it and I love it and I've taken some major risks and made some big investments to get to where I am. And everybody else thinks I'm really good at it too. I need to believe in myself to give my clients the confidence to believe me.

My partner knows all this and listens to me work all day long, since we live together and I work from home. But almost every morning, just as I'm about to sit down for work, she picks a fight and spazzes on me. Throws things around, says she's leaving, physically assaults me, cause me the most vile names and accuses me of the most foul acts.

I generally have a lot of control over my time and so what ends up happening is I take a couple of hours to bring myself back to baseline and then start working and end up having to work until late at night to put in the 10 to 12 hours a day and regularly do. That can't be right, can it?

If I wasn't numb to the situation and didn't slam a couple of beers as soon as I stopped working every night, I'd probably jump out the window. It doesn't help that I have chronic pain and don't take any pharmaceuticals, or that I've kind of stopped eating more than one time a day because I can't take backlash against using the kitchen to cook food in a normal way. Everything has to be so fucking difficult all the time, and I'm retreating into myself to protect my career and sanity...

That's it. Not asking for any advice or sympathy. That's in the post where it says I haven't been hugged in 3 years which I haven't posted yet. Hope everybody looks at this and thinks well, my situation is not quite that bad.
