@ramcowboy41, 5 Campden in 5 gallons is not a huge amount of SO2, so you
could restart the ferment. However, I agree with the previous advice -- call this one done. IME, messing with wines too much at the end, in an effort to fix things, may make things worse.
Accept this as a good lesson. Good? Yeah, your wine is drinkable and as suggested, you can do things to reduce the sweetness in the glass. Bad is pouring the entire carboy out! You have succeeded, even if the final result is not quite what you wanted.
@BernardSmith's advice is solid -- aim for an OG no higher than 1.100 in your next batch. Also, it can be difficult to get a high OG wine to ferment out. With the OG you had, it might have been difficult to get the ferment started.
My last mead was 15 lbs honey in a 6 US gallon batch, producing an OG of 1.089, which produced 12.6% ABV. I
might go as high as 1.100 on the next batch, but am happy with the last batch, so most likely I'll duplicate it (as much as anyone can duplicate a wine).
OTOH, if you want a high octane mead, start with 1.100. When the wine gets to 1.000, add enough honey to bump it back up to 1.010 and let it ferment back down to 1.000. You can repeat this several times, but understand that when you reach the end of the yeast's tolerance for alcohol, the ferment is done and whatever sugar left in the must is there to stay.
