Is the ConfirmID stuff difficult? (First time flyer)

I know I have to get the receipt and StateID for when I go up there. But I guess because it's my first time flying and I literally just turned 18, I'm kind of anxious they're gonna drop a nuke on me and require me to have something I don't have nor know how to get. So I'm bringing my birth certificate, SSN, W-2, and basically anything in my wallet. But the only thing that makes me anxious is my StateID doesn't match the address of my current address. If I bring my W-2 will that like cover it or anything? Also is this ConfirmID stuff difficult to go through? Getting a REALID is literally hell on Earth for me lol.
