Yahoo is being a dick

I don't normally bitch online about service that's free to me, but dammit, Yahoo Mail is seriously pissing me off these days. Attachments aren't uploading, and now this morning, it's just flat-out refusing to show me my Inbox mail.

Yeah, yeah, I know I'm not one of the cool kids for still using Yahoo, but I've had this account for ten years with nary a blip. Suddenly in the last few months comes the crazy. Feeling helpless.
