So freaking irritated!!

I've been doing weight watchers now for like 23-24 weeks. I've lost a total of maybe 7lbs? Why? not because I'm not exercising! I am actually! I walk 3 days a week-4 times total, I do crossfit 2 days a week and then Zumba one day a week. That part I have down. I can not get a hold of my eating! It's super frustrating cause I know if I did, I would lose the weight! I am not much of a healthy eater. I mean, it really takes work for me to eat healthy. When I go into the kitchen to get a snack or eat food, I go to sugar, chips, or anything unhealthy. Jake goes to the kitchen to get a snack and he grabs an apple and eats. Sometimes he craves sugar but he doesn't have the issue I have. I am trying to limit my sugar by only eating it on the weekends and I have already messed up on that yesterday! It makes sense, eat healthy, lose weight! So why can't I actually do that! Why is it so hard for me?? On top of it, I am bored of breakfast and lunch. Cereal, eggs, cottage cheese, and sandwiches are BORING! There has to be more!! I feel so stupid when it comes to food and eating properly. I so wish I could get a handle on my food! Have an ideas on how to help me??
