think you're being a bit hard on yourself tbh, the plan is a huge learning curve, at least you're counting your syns, and as everyone has said they're there to be used
you'll soon learn what you want to spend syns on and what you'd rather not, and what you can swap and save syns on
eg extra light mayo 1/2 syn tbsp - light mayo 2 syns tbsp
if its your first day cut yourself a bit of slack hun x
