Packing is Difficult

JUST 4 DAYS UNTIL I LEAVE! Words cannot express how excited I am. Let's just say, I've been working on packing for a few weeks now, and therefore living out of my suitcase. Fun stuff. But did you know how challenging packing for a month can be? Especially when you're travelling overseas. Anddddd especially when you're me.
For those of you who don't know, I'm a notorious over-packer. Like, by a lot. My family and friends all make jokes about it, and I have to admit they're right in doing so. But I think it's important to be prepared. As in, prepared for potential winter weather in summer (pretty sure I should bring my winter coat, just in case). And what if I drop something on my shirt, resulting in an impossible-to-remove stain? Better have a few more to replace it. See my thought process?
Since I pack like that for weekend trips, it's only logical that I should multiply that by 4 to equal a month's worth of necessities. But, unfortunately, we have been told to pack light. As in, pack as though you are going to be gone for a week.

...HOW DO I DO THAT?!?

Freaking out a bit, here.
I started by emptying my closet out onto my floor. When I realized packing was more complicated then that, I started eliminating "unnecessary" items. Now I'm down to: 1 pair of jeans, 2 pairs of shorts, 1 skirt, 2 dresses, 5 tops, a few undergarments, 2 PAIRS OF SHOES, and 4 pairs of socks. We're going to be able to do laundry there, thankfully. Oh, and there's also a few random items, such as duck tape (not a typo- I got some pretty awesome duck tape- and it's apparently a good thing to bring) and gifts for my host family.

I don't care what you say, this is packing LIGHT.

I'm hoping I'm done packing now, but chances are I'm going to go back through it all a few hundred more times and change my mind on what to bring. I have a feeling this is going to be the most difficult part of the experience. And, knowing me, I'll end up forgetting a lot that I should have brought.

JUST GET ME TO SPAIN ALREADY.
