I have an artisan vegan cheesemaking book by a woman named Miyoko Schinner. She has a good line of vegan cheeses in stores. She actually cultures her cheeses and has several aged cheese recipes as well.
I bring this up since you mentioned cheese making is a passion of yours. It might be fun for you to play with artisan vegan cheese making, and your background would allow you to easily tweak recipes to make cheeses you actually enjoy.
There's no better time to be vegan than now. There are so many products easily available that weren't even five years ago. The transition will get even easier the longer you stick with it. Really, it seems like you need something to get you fully committed. Watch some vegan documentaries like Cowspiracy and Earthlings. It'll give you the willpower you need to move on from your old diet. Eventually it won't matter what others think or say.

I've had the store bought cheese Miyoko's makes and it's incredible.
For half and half, do you use it for coffee? I recommend Silk creamer, the others I've tried aren't as creamy.
Miyoko Schinner's book has a cheese similar to Chao Slices based on Soy Yogurt, called Meltable Monterey Jack. I suppose you could substitute your tofu misozoke for the yogurt with some added water.
Her recipe adds water, salt, oil, tapioca flour and carrageenan powder.
np! also, if you are someone who will miss cheese, I hear miyoko is the best:

field roast chao cheese is also excellent! really adds to sandwiches etc. try making some grilled cheese with it. coconut herb is my fave
I stumbled across this recipe for vegan parmesan on Pinterest and fell in love with it. I make it constantly... double the recipe because I use it so much.
Helpful hints: if you don't already have one, invest in a good blender (I have this Vitamix ... love it), make your own coconut butter, when the 'parmesan' has hardened, use a rotary grater or a shaver instead of doing it by hand... otherwise the coconut butter will make it prone to melt from the heat of your hands.
