"I made muffins last night, and did laundry and homework. I mean, what week can go bad when it starts off with muffins, right? But I slept all day today, and I'm angry with myself."

Muffins are good, and laundry and housework are good.... and then you had to sleep the next day... ok. But that is the way it is sometimes. Don't beat yourself up over the low times..of course, that doesn't mean you have to wallow, either . But sometimes bad days follow good days, and if you need to sleep, then sleep. Make that sleepy day work for you, so you can be good for the day after that. You did real good once, you will get there again when you are ready.
