This is going to sound corny and silly (especially if you knew about the horrible holidays I've had and all the absolute negative poison I've slimed up my journal with accordingly the past couple weeks), but would it help if you tried to look at yourself as a friend would?
A friend wouldn't dwell on the chores; a friend would help you think up interesting ways to accomplish or get through the gotta-do stuff. A friend would give you encouragement about how well you can do so-and-so, which might just make you feel better about tackling the such-and-such.
Does that make any sense?

I'm up way past my bedtime, I'm tired, and I'm also just a wee bit spacey from a new fibromyalgia med, so if this post makes no sense, just kind of step over it... do be careful not to get any of it on your nice shoes.
