I'm another one, RMC.
Here's a little bit of advice I'd like to throw in the pot: Remember that you're under stress from this, and that means that your reaction time will be slowed, your decision making skills may be slowed as well, your attention span may shorten noticibly, and even (scariest for me) your reading level might go down a bit due to the attention thing, I think. So be more careful when you drive, don't make hasty decisions (including large scale impulse buying), write yourself notes so you don't forget things you need or want to do. I know you know that it's a good idea to drink alone. Do what you must, then do what you can, but don't push yourself. Sleep is good. And though some may disagree, I got the advice to avoid Country & Western music, even if you like it, as the subject matter can be 'way too depressing. If nothing else, turn on the classical music station on the radio (even if you don't care for the genre), as it's usually instrumental and less likely to bum you out.
While it's probably better to be discreet here on the 'Net with his identity, don't cover for him in the real world. You don't have to malign him, and I'd advise against it as bad tactics. Just let friends know what's going on in your life. some friends will fade away, but you will find true friends that you can talk to, who will be glad at those small triumphs that get you back to being you.
And I think I'll lihgt a !@#$-reduction candle for you in a couple of hours when I get home from work.
