My mind is such a jumble now

I feel like my mind is such a jumble now. I really can't get myself to focus on anything. And I think I had thoughts yesterday evening and last night that I had wanted to think about further, but now I've forgotten them. I didn't have a chance to write them down or I had assumed they were important enough that I'd remember. So stupid. Always write something down as soon as possible.

Hmm, I just need to pick something to focus on today. I hate that things can come up anytime and disrupt my plans though. That frustrates me to no end. I know that I'm suppose to be stoic and take things in stride. But it is so difficult.

Maybe I just need to catch up on sleep today? I know that lack of sleep affects me like this. So maybe that's all it is.
