It looks like you were reading it pretty close to right, kinda tough. To see exact but it looks like you are in the area of 1.096-1.100. And if it's sweet then yeah it's still a pretty high SG.
You may want to get another pack of 1118 and treat it like you're starting from the beginning, give it some nutrients, from what I was able to find you'd probably do well to increase the amount at least 1.5-2 times what is recommended and shake/stir the sh!t out of it, get it really aerated well, rehydrate the yeast with a tiny bit of the must, 1-2 tsp,and nutrients, 1/4 tsp, mixed in a cup of water that's about 104 degrees, let it sit 15 minutes, mix and pitch it and give it all another really good mixing.
From that point staggered nutrients and daily aeration until the SG drops to the 1.075 range then let it just go on its own and you'll be golden. Also you said it's real spicy, if it's more than you think you might want and you still have peppers in it, take them out now.
Watch and Listen to your Mead....It will tell you when the next step is.
