Welcome to the forum from Oregon.

Number 1, stop doing that and pay better attention.

Needs to get to a trusted shop and will need entire system drained and may or may not need a new fuel pump and remove injectors for cleaning. New seals and o-rings. May have or may not have affected the evap system.

Unhook fuel line, power the pump to evacuate all the fuel, put gas in it and then hope for the best. I doubt it does any further damage unless it was particularly dirty diesel. If you put gas in a diesel then you'd be having a much worse day.

I got diesel out of the premium pump once. We drove home just a couple of miles and it would not start the next morning. The station informed me the following day that the delivery driver messed up. Had it towed, the mechanic pumped the diesel out and changed the oil. Running fine probably 25k miles later.

Diesel in a gas motor wont ruin anything. Gas in a diesel is a disaster. Needs to be flushed out and it will run fine usually with fresh gas. Of course plugs out, fuel rails drained till you get gas at fuel rail, new plugs and go.
