I hate that shtick with girls. They just can't leave you alone because somehow you become the centre of their universe and unless you achieve what they want they feel that you somehow impede their own happiness.
Oh well, didn't want to go off on a bitter tangent. Krezack, I know what you feel like. I get scared of my inability to motivate myself to do much of ANYTHING, but I'll start sessions with a psychiatrist about ADHD soon. If I get a diagnosis and help, I suspect that will comfort me a bit and I'd feel that I'd get some control back, because I think once you start feeling like you're no longer in control you get anxious, and as a direct consequence of that, depressed.
I do, however, have this vague memory of reading that you already know you have ADHD, so maybe that stuff already is your field of expertise. In any case, I hope you get back on track soon.
