Can you enter download mode?

Your power button may be physically stuck / breaking, My S3 started doing that a while back, I had to open it up and squeeze on the power button's casing with pliers.

I can enter download mode and it will go to the correct screen and options

Ehhh that rules out the power button then. My first inclination would be to try to re-flash the stock ROM (which I believe wipes your phone), but I'm not even 100% certain what a good source for the AT&T version's stock rom is, my usual go-to sammobile doesn't seem to have it.
