Bereft...Lacking...And tense about it

Nothing on the needles.
You heard me.
Nothing.
Remember when I decided to have more than one project going at a time to avoid this horrid, empty, lack-of-knitting feeling? I just finished the BF socks, and last night I finished the Lotus Blossom Tank. Although it is desperate for blocking and therefore not done, it still qualifies as a finished object: Knitting is complete and ends are woven in. All it needs as a wash and a lay-flat...With perhaps some steam iron manipulation.
In the basket I have several ziplocks and patterns awaiting me:
* 2 skeins of beautiful variegated sock yarns which cry out for lace socks or chevron patterns.
* A bag of gorgeous celedon silks and mohairs which I have envisioned, yet not yet swatched, as fingerless gloves.
* A bag of black cotton for my dear friend's Kyoto sweater that I have been procrastinating from.
* The Interweave Knits opened to the Icarus shawl, and not quite enough Rowan haze to complete it.

I am thinking I should start all four of these projects. Obviously, two projects at once is not enough to fend off the finished-object-blues. I see my error: I was too excited to finish both of the projects. I completed the socks in a flurry of excitement to get them on the feet of my beloved. Left with only the stockinette top of the tank and a bunch of Netflix, I quickly slid that one into home as well.
The above projects offer enough variation in difficulty, materials, portability and pattern to offer enough distraction for a bit, and even if I rush through two of them, I will still have two more!
Is UFO-guilt better than empty-needle-blues?
Is this how people end up with a closet full of UFO's? As emotional insurance?
