I'm a Monday weigher, but we are all always here to help each other out and support each other.
SW is a healthy eating plan more than a diet I think. Your can still have the 'naughty' foods, just in moderation. It's about creating a lifestyle change and encouraging people to cook from scratch more rather than frozen foods and jarred sauces.
And Please don't be worried about going to group, I absolutely love mine and I've made some great friends there too. And if your first class is this week then I would imagine you will get a group 'new member talk'. The talk is usually done to just the new members, but as it's the first week back after Christmas, and there will be lots of new people in the majority of classes, everyone gets a new member talk to the whole group (or i assume it will happen in all groups as SW recommend it to happen
So there will probably be a few other nervous new people along with you
give it a few weeks at least, if it's not for you you can change to online but I hope you'll enjoy it
With regards to your food plan, this is what I can work out regarding the Syns:
4 Syns for the second slice of wholemeal bread
I'd count 6.5 Syns per 100g of sausages
Uncle bens wholegrain rice is 3.5 Syns for the pouch, so count 2 for that (better to count over than under!)
You get 5-15 Syns each day so you should be ok with what you've got planned
It's always tricky when you've got all those foods in the freezer etc, but you can still eat them, it's just about trying to figure out the syn value and work them into the plan.
Failing that invite people round and feed it to them
The only think I'd suggest is maybe growing in some mushrooms or tomatoes with your breakfast if you can, the more speed food the better the losses
