No worries, dude! I'll definitely offer up the advice someone told me: make everyone tell you "No." Apply everywhere you'd consider applying to and to every airframe you'd think you'd enjoy flying. You're not out of any fight until they definitively have told you, "No," and closed the door on coming back for another application period.
Unsponsored is good and you might have a leg up getting hired if you're already through OTS and here at UPT, because you've got pilot community connections helping make connections at a unit and an interested unit just has to agree to pick up the tab. In the Guard pipeline, this is doubly so, as they have to fight for each training slot (OTS, IFT/SERE, UPT, etc.); the Reserves just have you shunted to the 340th, which handles all training for all Reservists, regardless of the squadron.
On the downside, until you get picked up, you're at the whim of the Reserves and don't have a "champion" of your cause. If you're picked up by a unit before starting the ride, you'll have them in your corner if you hit any bumps and to help push your paperwork.
Pros and cons to both. Either way, just keep doing all you can to get that spot!
