I'm exhausted

yesterday was my appointment with the disability doctor. After some really embarrassing moments (he asked me what the capital of Italy was, and I, without hesitation, said "Paris". I then look at him funny and say "Wait, did you say Italy? That's Rome") He said that at least I corrected myself. It just sucks. I was in a deep, horrible hole of depression a couple days ago, and when it came time to see the doctor I was fine. 
I went a bit hypomanic this morning, and now (5pm! damn it's late) I'm emotionally crashing hard. I'm having trouble staying vertical, but a guy is working on Geo's car and he only speaks Spanish. Geo doesn't speak Spanish, so I'm the only one who can talk to the guy. As soon as the guy leaves, I'm lying down. Geo is lucky and napping. I want to be there with him, but I have to stay for Frank (the guy helping us with the car). 
I started feeling really dizzy, so I made myself some tomato soup... so it's not from lack of food... I'm just dealing with depressive exhaustion.
