Sick of this time, sick of this place

I've pretty much had enough this week. Weirdly, I don't feel particually depressed but for once I'm recognising the signs.

I've lost all motivation with life, even at work. That's been going downhill for a few weeks and I had hoped things would start to improve on their own, like they normally do, but it's just not happened. I'm struggling more than normal to get out of bed in the mornings. I have no interest in the work I'm doing and am doing the bare minimum to get away with it unnoticed, my hours have reduced because of it so I owe the company time. At home I'm not making any effort, the house is filthy and full of clutter (I'm a hoarder anyhow) and it sickens me. Even tonight, I went to start to clean and tidy the bathroom, thinking to myself that if I start it, I'll get some motivation and will finish. But I got as far as taking everything out of the bathroom (plants, clothes etc) and no further.

My eating is all up the spout. I've been doing Weight Watchers since August & doing reasonably well; it isn't too difficult, it makes sense, it encourages you to eat healthily and doesn't encourage you to eat processed crap (like ready meals, diet or low-fat foods etc). I'd even managed to get in control of my eating disorder. But the last few weeks I have lost that control again. I have been making myself sick regularly (which I haven't done on a regular basis for a year or more) and I am using a scary amount of laxatives and although I'm not using them day-in-day-out, if I do use them, the "starting" dose is so much higher because I have been using them more and my body has built up a tolerance.
