Thanks guys for the great advice and support. I'm going on vacation tomorrow so I'll hopefully see the brighter side of life through that. And I've a therapist appointment soon after I return.
I got to stop posting when drunk (doh!). It's not a dependency yet but I do turn to it every so often to fight my mind racing and as a sort of act of protest (like a crazy scream into the night or punching a wall - if that makes sense). I'm so responsible though in general that I would be very surprised if I overdid it too much.
Thanks again guys. :-)
