Chocolate Guilt??

I just finished my lunch at work and still needed something else to eat as I felt that I wasn't satisfied with the crap sandwich and the even more crap yogurt that I had decided to have for my lunch last night.  Looking at everything they had on offer at the counter I decided on a chocolate bar.  Now, after having been back for 20 or more minutes I feel guilty about eating the chocolate bar.  Since when has weight watchers taught me to be guilty about eating a chocolate bar?  It's also going to encourage me to eat a salad for tea when all I really want is Tesco's Mac & Cheese.  Don't get me wrong I like a salad as much as I like the Mac & Cheese it's just that I'm having 'one of those days' and eating a chocolate bar can make things turn into a really bad day.  God only knows what's going to happen if I do have this Mac & Cheese for tea.

Is it even weight watchers that is making me feel guilty about eating the chocolate bar?  Could it be the fact that everyone is saying that I don't need to lose weight and that I'm fine the way I am and it's getting to me slowly?  I'm still losing and gaining weight most weeks but I'm not maintaining.  It's getting me down which is making me want the chocolate that's making me feel guilty.  Do I need to move classes and get a new leader who's more encouraging towards you  and less annoyed because she 'doesn't get paid as much' because no one is losing weight?  I know that part of the guilt is because I know I can do better and eat better but because I'm so freaking tired it's just easier to have the ready meals and stuff that are filled with crap.  Also with friends telling me I should cook my own meals all the time, I would but I work full time and don't normally get home till 8 maybe 9 at night and then can't be bothered to cook from scratch, cooking before hand and freezing or putting it in the fridge would be an option but not when I'm living with my parents.  We have limited fridge, freezer and cupboard space in the house as it is without adding a weeks worth of food for me.  Also mum and dad are not willing to have the same food as me every week.

Alas I am now finished work so must go and get weighed.
