Default NEED HELP. I think i have water in the gas tank

As the title states, I filled up this morning at the Shell station off the 14 hw Golden Valley exit. When I drove off the gas station...it started the a couple of seconds later my car starts acting up. I thought my car was cold or just acting up. I started driving and my check engine kept turning off and on. I was late for work so I kept driving the car. When I got home I scanned the car with my OBD2 and found 5 codes.
1-P0420
2-P0303
3-P0304
4-P0300
5-P1399

What should I do? Do you guys think there is water my gas tank? I did not put diesel in my tank, I put 91 octane.

I forgot to mention my car runs very sluggish and with low power. It also sounds like a WRX, not to offend anyone.

water is a possibility but so is diesel, is there ant redidual gas at the filler neck? Does it feel a little oily.? Sometimes people get in a hurry and grab the wrong nozzle or the tanks at the gas station were contaminated. Either way the car runs terrible or won't start and the tank needs to be drained.

You'd be surprised that sometimes the tankers "mess up" and put the wrong fuel in the in ground tanks...

Diesel in gas and gas in diesel...

Thanks everyone,
My car starts fine, but it runs like a moped. When I drove back in traffic, and the traffic cleared, my car went 70 mph+. But, like I said it took a long time to get it up there. Is this a DIY or should I go to a mechanic. I will definitely check my spark plugs. Anyone know how much will it be taking it to a mechanic?

Stop driving the car before you FUBAR things up.

First off smell your gas tank. does it smell like gas or diesel? If diesel then the station has diesel in the premium tank which is bad. Call them...
