I'm sorry things aren't going smooth! For the weekly points - it's different for everybody. Some people eat every one of them and some can't eat any. I think the main culprit here for you is that you ate them all the day before you weighed in. If you had salt and sugar, then it's most likely that you have water retention, or if you ate late, it could be undigested food. Most likely you will see it differently next week!
For zero point foods - are you eating extra servings of fruit and veggies each day? Zero points still add up the calories - for most people it's not a problem, but if you are eating way more than 5-6 servings a day, it could be adding up.
Are you now eating foods that you didn't eat before WW? Like - frozen dinners, snack bars, or other convenience foods? I have a big problem with refined flour, white rice and sugar. Weight loss is practically impossible for me when I eat those things (I've got PCOS and I'm insulin resistant).
Are you tracking every single bite? My WW leader has a mantra - Only track your foods on the days you want to lose weight.
If you'd like to share your food logs, maybe we can shed some insight!
Hang in there.
