Thanks for the pep talk, guys. My supervisor asks me about my EAD everyday, so the eagerness to get it in my hands so I can get back to work is what had me on edge.
The status still says "Sent out for delivery", so I'll contact the post office about it tomorrow in the hopes that they still have it, and that it's not lost. I'll keep you guys updated.
And Eva, I need to stop complaining because I just noticed that yours may not have been shipped yet

I seriously hope it does soon. It's a painstaking waiting process.
