If you do nothing else but wait, you will still have drinkable beer. If it's your first batch, you will likely be surprised that the beer is better than you thought. It may have a fusel alcohol taste, which it will taste like good beer with an off after taste. Drink this batch and learn what not to do next time.
For now, make sure to ferment in the mid to low 60's. If you can't put it in a colder location, take the whole fermenter and put it into another larger container of water. Add ice to the water bath outside of the fermenter, and try to get the temperature down to the mid to low 60's.
I've pitched hotter than planned before (even recently), but never that hot. I have a temperature controlled freezer, so it wasn't a huge issue. In your case, I would really do your best to keep it cool. Read up on temperature control and pitching temperatures. It'll pretty much tell you what to expect.
