A day like you had is not the best way to get back into brewing. Not a total disaster though. Some planning and you will be ready for the next one.
The yeast could be a little stressed but not much. You could make a quick half liter vitality starter while the wort is cooling if you have some DME on hand. 50 grams to a half liter. Probably won't get a krausen forming before your wort is down to the low 60°F range to pitch the yeast. It will give the yeast a start though.
Do you have snow where you are located. Set the fermentor in tub and add snow with some water for faster cooling. Next brew day you could have gallon jugs of water at near freezing to top off in the fermentor. Some ice for the tub to set the boil kettle in.
I had been pouring the chilled wort from the boil kettle through a funnel with a strainer into the carboy. My wife would sit in a chair to hold the funnel up right. A piece of copper wire in the mouth of the carboy for displaced air to escape through rather than burping in side the funnel.
Now I pour into a bucket that holds a mesh bag for straining. Tube from the buckets spigot into the carboy. I think I put pictures of old way and new way in the DIY category.
This is just a quick response. We can surely solve your brew day problems so you can look forward to the next one.
