Overwhelmed/Stressed

Feeling overwhelmed right now. Not sure if these are the root causes, symptoms of a bigger problem or what. I'm just dumping it out:
-All the things that have to be done before DD goes to college (buying linens, getting computer maintenance plan, list of things she'll need, making sure she does all the things she needs to do)
-debt. Cars keep having problems; can't seem to pay down the credit card - again.
-dog bit DD. Didn't draw blood, but still, the fact that he did it...
-the dog's failing health. Will I know when to say "it's time"?
-need to give the dog a bath.
-My son... no changes. Maybe going through his driving classes that DH enrolled him in may help. But are my expectations realistic?
-yard work. Can't seem to keep up with it. Hedge trimming, weed pulling, edging the garden, hanging plants seem to be dying for no good reason.
-house work. That too. I have no motivation to do any "deep cleaning" though it feels like it's hanging over my head. Hard to keep on top of the every day stuff.
-blog. I want to keep it up weekly. Once I get in a writing groove, I really enjoy it. But it seems hard right now.
-Genealogy. I have so much inputting to do, so many documents to review.
-work. Lots of projects, no end in sight right now. Good not to be bored, but I do miss having some unstructured time.
-cooking. I would love to have the motivation to cook, but I don't. I want to eat healthy, but again that cooking motivation...
