Why I'm Overwhelmed

I am not a sloppy person. In fact, I really enjoy order, though I am by no means a perfectionist and can turn a blind eye to most anything if I'm not in the mood to deal with it. However, there are some areas where I am just really not good at keeping order and one of those is organizing clothes, particularly the clothes that the kids have grown out of. And I've done such a poor job of it over the years that I am now completely overwhelmed and feel like I'm having a panic attack every time I look at this:

And this:

Yes, that is a pile of clothes stacked up the the nursery next to the crib and in the closet that Tia and Landon have outgrown. Only Tia and Landon - that doesn't include Sloan's clothes - I haven't really gone through his yet so his drawers are busting with clothes, as are Tia's as you can see here: Because Sloan and Landon were born in different seasons, a lot of Sloan's stuff didn't fit Landon. Now, however, he's getting to an age where things are going to start working. Here is the problem - I have about 12 Rubber Maid tubs in our basement filled with clothes, but they are not really categorized by size - they are to an extenet, then I got lazy and just started tossing stuff wherever it would fit. So, poor Landon is squeezing into smaller clothes because I don't want to buy him new clothes until I survey what I already have. But I don't know how to survey what I have without taking it all out and stacking it according to size, which would take up a massive amount of space which means I would then need to be prepared to put it all back in some sort of order which means I need about two days without any kids underfoot because I cannot possibly take on a task like that and still try to keep up with them...*gasp, wheeze, puff* I go back and forth about whether or not to have a garage sale and just get rid of most of it, which, again, would take time to organize, which leads me back into my cycle of panic. But I am not quite ready to get rid of everything yet. I'm pretty sure Lee and I aren't going to have any more children biologically but part of me fears that if I get rid of everything I'll pop up pregnant a month later, like I'll have some gigantic target on my back or something. It's also just hard to get rid of the baby stuff because it means it's over for good. I know that's silly, but I'm just not quite there yet - but I am getting there so we'll see. No matter what, though, something has to be done and I don't know how to get it done. Thus my need for a paper bag and a dark room. I just don't know where to start. Ahhhhh! Okay, now that I let that out, I'm going to take a deep breath and shove this to the back of my mind for a little while longer. Maybe if I ignore it long enough it'll all just go away...
