Thanks everyone. I feel much better now; I couldn't sleep last night, so I spent 3 hr straight on the internet, distracting myself. Then I went to bed, and got up at 12:30 even though I'm supposed to work at 10:00. I texted my boss, apologizing for being so late to work; he texted back saying that he wouldn't be in today at all, because he was sick, and I should just take the day off.
So I don't have to work, I've went to the pharmacy and gotten and taken my meds, feeling better already. Maybe I just needed to let go for awhile? I've really been focusing on self-improvement lately, on becoming a perfect, responsible proactive person, and I think I was a little overwhelmed by that. Being off my meds just exacerbated it...
So glad to be feeling better; thanks again for all your support!
