Oh L.! I so get it!
There have been times in my life that either I was so full of her that I could not take one more bite, or so empty, I had nothing left to give.
Don't have any morsels of advice here, some days are like that, espeically when it is cold, and the nights are so long. Something about winter makes it seem like I spend more time with my kids.
When mine was little, someone was watching her run circles, and they said "do you drink?" and I said "no" and they answered "you should!" Go have a glas of wine and a bubble bath. Tomorrow will be better (we can all hope!)
If not, someone who spends less time with her than you do will probably tell you sometime soon how "delightful" she is. I always say how much I would like to meet that kid, cause I have never met her! Anyway, it is good for a lift!
Hope it gets better soon.
