thank you all SO much for your replies!! i appreciate them greatly!!!
it's been a couple of weeks since i first posted this and already things are going a little more smoothly.
i stocked up on meat (at the farm where i work) and have been pulling stuff out of the freezer on sunday and either cooking it then or getting it prepped to cook during the week.
i've surrendered to the fact that - at least for now - i am buying more convienence food than i like to. little containers of yogurt have been a big hit with the kids on hot days. (we have access to fresh milk, and at some point i will be making my own yogurt but i'm just not there yet.) and granola bars -- lots of granola bars!!
i also cut back my hours a bit so now we're only doing one market a week, instead of two, which is making a big difference. the long market days (8+ hours to load up everything, travel, be at the market, travel and unload back at the farm) in 95 degree heat was really taking a toll on my and my kids.
the bartering idea is great. i know some farmers who do that at their csa -- give someone a share in exchange for having them prepare (or preserve) some of the harvest for the farmer's use. definitely something to ask around about!
i'm also enjoying the post-market trading that happens between vendors. this week i came home with some yummy salsa and two loaves of bread. we gobbled up one of the loaves last night for dinner (with some goat cheese and pesto - yum!) and i'm going to freeze the other one.
so yeah...not feeling quite as out of control this week. just moving forward with lots of little baby steps, and trying to be gentle with myself this first year!!!
thanks again for all your replies.
